Improving the quality and effectiveness of welding by utilizing the standardISO 3834 – Guideline for company implementation

IIW Keywords: ISO 3834, Company Certification, Quality Management, Checklist,

Questionnaire

Objective The objective of this publication is to provide companies intending to apply the standard ISO3834 dealing with the quality management of welding, advice on the kind of procedures andforms that might be beneficial to them and on the content of such procedures. This publicationprimarily deals with the adoption of ISO 3834-2, but much of the advice is also applicable toISO 3834-3 and ISO 3834-4.

This publication does not mean that all the procedures presented in it are necessarily required.

Once the company has thoroughly considered its needs and has decided that it requires acertain procedure, this publication can be used in order to find advice for the preparation of theprocedure. The publication should not be used as requirements for procedures or check-lists inconnection with audits.

Abst ract

This publication is primarily intended for people who are responsible for quality control in thefield of welding. Because the items presented in this publication may have a significant impacton a company’s business operations and their successful continuation, the publication will be auseful tool also for strategic and operational managers. This publication also deals with matters

relating to the sale and marketing of products. Therefore the sales personnel of weldedproducts shall understand, in order to ensure that the products sold are manufactured inaccordance with the designs, in a controlled manner and with minimal risk.

ISO 3834-1 gives the instructions for the selection of the level of quality requirements, whileISO 3834-2, 3, and 4 present quality requirements of different levels. Manufacturers of certainwelded products, such as pressure vessels, offshore structures and steel structures, may needto comply with the quality requirements of ISO 3834 required by applicable product standards.Foreign customers may also require compliance with these requirements as well as majorexport companies of their own subcontractors. A company may gain considerable benefit fromapplying these standards, even without third party certification. It is possible to certificate thestandard ISO 3834-2 as part of ISO 9001 quality management system or ISO 3834-2, -3 and -4can be certificated on their own.

ISO 3834 presents systematically and comprehensively the factors and measures having animpact on the quality in welding, which a company can develop in order to improve themanageability of its production, the quality of its products and the reliability of its lead times aswell as the cost-effectiveness of its manufacturing process. For the company it is important toidentify properly those items that will be subject to the requirements presented in ISO 3834-2,3, and 4. The aim is to avoid unnecessary documentation and procedures and ensure that thequality management is appropriate for the welded products to be manufactured. Thispublication gives examples of the key procedures and the related work instructions and forms.

The key issues to be taken into account in the quality management of welding:•Technical review verifies the company’s capabilities for manufacturing the product that has

been ordered and identifies particular welding requirements related to the contract. Only acorrectly conducted technical review ensures well-managed, risk-free and cost-effectiveproduction.

•Competence requirements specified for the welding personnel will, in the case of someworkshops, be clearly different from present practice. Product liability gives additionalemphasis on the responsibilities and role of the welding coordination personnel. Therequirements relating to qualification of welders and welding operators strengthens the qualitymanagement of welding and can also reduce costs caused by errors. The standard may notbring any significant changes to the current practice regarding inspection personnel.

•Production plan and qualified welding procedures assure that production is carried outsystematically and the characteristics of the welded joints meet the specified requirements. There are several alternatives for the method of qualifying welding procedures and thecompany shall apply the one that is technically and economically the most appropriate for theproduct concerned.

•Descript ion of production and testing equipment used in connection with welding allowsthe company to check the suitability of its equipment pool for the manufacturing andinspection of the product it sells. Acceptance tests of equipment, regular maintenance andpossible calibration or validation, in order to ensure that it will be possible to follow thewelding procedures sufficiently and that the inspection and testing results are reliable.

• Systematic dealing of non conformances ensures that a defective product is not put intoservice by mistake. The reasons for non conformances are analysed and corrective actionscarried out in order to prevent similar non conformances in the future.

Adopting ISO 3834-2, 3, or 4 requires considerable time and effort by the company, with all thepersonnel being committing to the work and the additional activities required: developing workpractices, performing new duties, ensuring the flow of information, etc. When theimplementation starts it might be advantageous to engage external expertise in order to obtainan objective picture of the starting point. The company may decide to focus on reaching a pointwhere the conditions are fit for certification by documentation and procedures for tasks andactivities, but the real economic and technical benefit from the adoption of ISO 3834 will beachieved only when the activities and content concerning the welding work are developed. Forthis reason, ISO 3834-2, 3, and 4 should be understood primarily as a tool for developing the

welding activities in the company.

1 General

Welding is a general production method for manufacturing of metal products. Welding has aconsiderable impact on both the product’s costs and quality. Consequently, it is important thatthe welding is carried out as efficiently as possible, meeting all specified quality requirements.

Weld quality is achieved by sound welding, not by inspection. Inspection, however, provides acheck of the reliability of the product, but cannot improve poor quality. Welding requirescontinuous control and/or to follow documented procedures. On this basis, the ISO 3834 seriesof welding standards has been prepared.

The purpose of the ISO 9000 series is that the company designates as a special process anywork where the final quality of the product cannot be verified only by inspection. If qualityrequirements are specified for the welds in the product, it is appropriate to define welding as aspecial process.

It shall be observed that ISO 3834 is not a quality control standard that replaces ISO 9001, butmore an auxiliary tool for applying ISO 9001 in companies which carry out welding as a specialprocess. In such a case, the additional compliance with ISO 3834 will be included by areference in the ISO 9001 quality system. It is also possible to obtain certification under ISO3834 without any linkage to the ISO 9001 quality system.

The standards are general and not fixed to any certain product. The series of standards refersto three different levels of quality requirements:

- ISO 3834-2 Comprehensive quality requirements- ISO 3834-3 Standard quality requirements- ISO 3834-4 Basic quality requirements.

Guidance for the choice of level of quality requirements is given in ISO 3834-1. ISO 3834-5specifies documents and standards necessary to consider in order to claim conformity to ISO3834-2, 3, or 4.

2 Reasons for using ISO 3834Regulations

Regulations, eg, EU directives, define safety requirements on products and structures. Productstandards present the technical solutions that serve to fulfil the safety requirements specified inthe directives.

Product standards

Many European and some International product standards refer to the different parts of ISO3834 regarding welding. For example, the standard concerning pressure vessels (EN 13445)states that the manufacturer of the pressure vessel is obliged to fulfil as a minimum the welding

quality requirements given in ISO 3834-3.








5

The European standard EN 1090-2, dealing with execution of steel structures, requires the useof quality requirements according to ISO 3834. The level of quality requirements depends onthe execution class.

Customers

Once ISO 3834 is in use, companies could utilize it for marketing purposes and customersmight require certification to ISO 3834.

The welding company (manufacturer)

The welding company wishes to improve its welding quality management system, increaseproductivity and, by applying quality control in welding, demonstrate to its customers to be areliable supplier.

Main contractors

A subcontractor working to ISO 3834 can expect to have a significant advantage over itscompetitors, when a main contractor is outsourcing its welding or welding related activities.

ISO 9001

ISO 9001 states that, where necessary, special processes shall be identified. Welding istypically considered as a special process. This requires that specific requirements, which arespecified in advance, are fulfilled. ISO 3834-2 is an excellent tool for doing this.

3 Choice of quality requirement level

ISO 3834-1 gives guidance on the choice of level of quality requirements.

When a welding company uses a quality control system conforming to ISO 9001, thecomprehensive quality requirements according to ISO 3834-2, 3, or 4 may all be selected. There are only small technical differences between ISO 3834-2 and ISO 3834-3. The maindifference is the level of documentation. ISO 3834-4, presenting basic quality requirements isthe level of choice when the welded components have a low safety risk. Product standards andnational codes may also give references to the different parts of ISO 3834. Table 1 gives ashort summary of requirements for ISO 3834 in European product standards.

Railway vehicles (EN 15085) Certification level 1 ISO 3834-2Certification level 2 and 4 ISO 3834-3

Certification level 3 ISO 3834-4Off shore (NORSOK) ISO 3834-2

Water tube boilers (EN 12952-5) Recommends parts of ISO 3834-2

When applying ISO 3834, it should be noted that all of the items presented in the standards donot need to be implemented, if they are not relevant. In such cases clear reasons shall be givenfor such a decision.

As a basis, it might be appropriate for a company to start applying the ISO 3834 by adoptingthe requirements of ISO 3834-2 and identifying those items that are relevant from thecompany's point of view. Care shall , however, be taken to ensure that the quality requirementsspecified are not lower than those presented in ISO 3834-4.

The company may also apply different levels of quality requirements for different products.Although the company may have adopted the standard ISO 3834-2, it may decide to applylower quality requirements according to ISO 3834-3 or ISO 3834-4 in respect of certainproducts or certain production lines.

4 Procedures and forms

4.1 GeneralQuality control may be described at three different levels:

At the general level, a description of the company’s organisation, areas of responsibility,operation, equipment, personnel, etc. is given.

At the procedure level, the way in which the activity has to be performed is described as well asresponsible persons.

At the level relating to forms, the necessary forms, lists, reports, records, certificates anddetailed working instructions are prepared.

Often the company is not familiar with preparing procedures. The procedures should be as

simple as possible. A good procedure fits onto a single A4 sheet and is clear and conciseenough to be read without sitting down.








7

Not every item needs a procedure. Sometimes it is enough just to know how things have to bedone. It is often difficult to decide whether only knowing how to do things is enough or whetherwritten procedures are needed. Written procedures are needed, when people ask a lot of questions, different people do the same task or when lots of mistakes are made.

4.2 Purpose and content

The purpose of procedure is to:• ensure harmonised and effective working• establish responsibilities in respect of tasks and work activities• act as the practical starting point for preparatory work• provide information• act as a channel for exchanges of experience.

Procedures include e.g:• purpose and scope of the work activity• what is to be done and who does it (content of the procedure and the person responsible forit)• when, where and how the work activity is carried out (content of activity, person responsiblefor it)• materials, equipment and documents that are in use• how the work activity is managed and documented.

4.3 Relevant procedures and forms/check lists

Table 2 gives procedures and forms that are appropriate according to different clauses of ISO3834-2. Where necessary, they can also be used when applying ISO 3834-3 and ISO 3834-4.

It may not be necessary to apply everything that is presented in Table 2; the company has fairlyfree hands to make the appropriate choices. Under no circumstances must the table be usedas audit requirements.

The procedures provide examples of who could be the person responsible for certain workactivity. The examples are completely arbitrary. It is important to nominate the person andensure that the person is aware of his or her responsibilities and is also given the appropriate

power to act.

2) Example see annex B4.4 Review of requirements

The procedure for conducting the review of requirements concerns the part of the contract thatdeals with welding. The purpose of the review is to ensure:

• that the company is technically and otherwise capable (e.g. delivery schedule) to fulfilall the requirements and wishes presented by the customer and

• to check that all the fundamental requirements relating to the welding of the product arerecorded.

The review of requirements shall be conducted before any offer is submitted. The review of requirements is the responsibility of the person, e.g. sales manager or projectmanager, who goes through the orders and the proposed contract. It is important for thewelding coordinator to be present when matters concerning welding in the contract are dealtwith.

If there are ambiguities in the order or in the proposed contract, the person in charge solvesthem together with the other parties and with the customer.

In the review of requirements the relevant items presented in clause 5.2 in ISO 3834-2 arereviewed. It is useful to draft a form for dealing with the matters below. If the company haspreviously supplied an identical or similar product, it is not essential to complete the form in

respect of each individual contract.a) Product standard to be used, together with any supplementary requirements:

• does the product relate to any directive?








11

• does a product standard exist (e.g. ISO-, EN- or national standard)?• does the customer have an existing product standard?• quality level and acceptance criteria?• the mechanical, thermal and/or chemical characteristics set for the welded joints• any additional requirements?

b) Statutory and regulatory requirements

• does the product relate to any regulation?c) Any additional requirement determined by the manufacturer

• any additional requirements?

d) The capability of the manufacturer to meet the prescribed requirements

• new project?• review of resources?

4.5 Technical review

The purpose of the procedure for the technical review is to look at the matters that shall betaken into account when reviewing the contract. The procedure deals with matters concerningwelding.

Each company has to nominate the person who will take responsibility for these matters. Thatperson may be, for instance, the main project designer. The welding coordinator shall bepresent whenever any welding matters are discussed.

The following issues should be resolved before the procedure is prepared:• has a technical review been conducted previously (have earlier experiences been taken intoaccount)?• what are the differences in relation to previous requirements? (any fundamental changes?)

The technical review should cover at least the matters presented in clause 5.3 of ISO 3834-2,as described in the list below. If the product in question has been manufactured in the past, it isnot always necessary to review these matters again.

a) Specification of parent material(s) and welded joint properties:• weldability

• chemical composition• strength• ductility (impact, tensile)• thickness of material• corrosion resistance• wear resistance• high temperature characteristics• quality of parent material surface• other characteristics

b) Quality and acceptance requirements for welds:• quality level• acceptance level• acceptance criteria for welding tests

d1) Welding procedures:• do all necessary welding procedure specifications exist?• are welding procedure specifications required for all the joints?

d2) Written procedures for non-destructive testing (NDT):• will non-destructive testing (NDT) be conducted?• will the company perform the necessary non-destructive testing itself?• do the necessary written procedures exist, e.g. NDT standards, for the NDT methods to beperformed?

d3) Heat-treatment procedures:• are procedures needed for pre-heating and/or post-welding heat treatment?• will the company perform the necessary pre-heating/heat treatment itself?• are there appropriate procedures for pre-heating/heat treatment?

e) The approach to be used for the qualification of welding procedures:• how should the welding procedures be qualified (e.g. ISO 15607)?• additional requirements (e.g. product standards)?• acceptance criteria for the welding procedure test• are there any appropriate qualification records available?

f) Qualification of personnel:• is there a responsible welding coordinator?• do the welders have valid certificates for the job in hand according to ISO 9606/EN 287 orother applicable standards? Are additional requirements necessary (e.g. product standards)?• are the welding operators qualified according to ISO 14732/EN 1418 or other applicablestandards?• are the NDT inspectors certified according to ISO 9712 or EN 473

• are there any requirements for qualification of persons carrying out heat treatment?g1) Selection of material, identification and/or traceability:

• what is the parent material?, availability?, weldability/special characteristics?• supplier, approved?, known?• how is the parent material identified (transfer of marking)?• should the parent material used in the product be traceable?• are material certificates required? (what level?)• approved parent material/filler material• filler material? (test reports?)

g2) Selection of welders:

• does the work require a welder who has a valid certificate for that particular welding job?g3) Identification of welds:

• do the welds have to be identifiable? (to the welder?)








13

h) Quality control arrangements, including any involvement of an independent inspection body:• is external quality control required during manufacture?- customer?- third party?- when?

i) Inspection and testing:• which parts will be inspected or tested?

- scope of inspection- inspection methods- inspection stages- reporting level (everything, deviations, errors)

k) Post-weld heat treatment:• has the company taken into account the quality requirements presented in ISO 17633concerning heat treatment in connection with welding?

l) Other welding requirements:• production weld tests• batch testing of welding consumables• determination of ferrite content of weld metal• ageing• hydrogen content• sufficient information on permanent backing• peening• surface finish• weld profile (undercuts, smooth transition, shape of root, convex weld (grinding)

• welding planm) Using special methods:

• root opening• root gas• buttering

n) dimensions and details of joint preparation on completed weld:• type of joint• type of joint preparation• groove preparation• tolerances

o) Welds which are to be made in workshop, or elsewhere:• where final installation takes place (on site)?• are the components produced in different workshops?








14

p) Environmental conditions relevant to the application of processes:• low temperature• wind• moisture• lightening

q) Handling of non-conformances:• how to act in case of a non conformance?

- additional inspections (can the number of inspections be reduced?)- alternative inspection methods

• how to proceed if modifications are required after the contract stage?- who is authorised to approve the changes?- documentation of changes?

4.6 Sub-contracting

If the company intends to use sub-contracting services (e.g. in welding, inspection, NDT, heattreatment, calibration, maintenance), he shall provide the subcontractor with all the relevantspecifications and requirements. The sub-contractor shall provide the documents and recordsspecified by the manufacturer concerning the sub-contracted work.

4.6.1 Sub-contracting of welding

The procedures on sub-contracting shall ensure that the sub-contractor has the technical andqualitative capabilities (capacity and know-how) to manufacture the product such that theproduct meets the requirements specified by the actual customer, comply with the appropriateitems of ISO 3834 and that the timetable requirements will be met.

The person responsible for the sub-contracting matters of the company has the responsibility toensure that the sub-contractor meets the technical preconditions required of manufacturing. This person should use experts in the company, e.g. the responsible welding coordinator.

Scope of sub-contractor assessment

Only the part of the subcontractor's technical know-how has to be assessed as required for thesub-contracting work. The scope of the assessment depends on what kind of quality systemthe sub-contractor has in use. If the subcontractor works according to a certified quality systemincluding ISO 3834-2, it will be enough just to conform the technical competence (capacity) andto check the equipment. A sub-contractor without any documented quality system should besubjected to a separate quality audit conducted by the company.

Items to be addressed wi th the sub-contractor

Review of requi rements

A review of requirements with the sub-contractor may be performed together with the technicalreview. A review of requirements may include the following.

a) Product standard and possible additional requirements to be applied:• the sub-contractor needs to know what standard and requirements the product has to fulfil.








15

Technical reviewA technical review shall be performed with the sub-contractor wherein all the essential aspectsrelated to the sub-contractor's work will be addressed. Consideration should also be given toany earlier technical reviews or similar reviews. If there is significance differences or changes inresources of the sub-contractor an assessment is necessary. A technical review may includethe following.

1) Welding procedure specifications:• The sub-contractor's welding procedure specifications need to be checked. If they are notsuitable for the product to be welded, the sub-contractor shall qualify new welding proceduresto comply with the product and based on these qualifications new welding procedure

specifications shall be prepared.• Assessment to be made whether it is possible to use the main company's weldingprocedure specifications (standard procedures)

2) Non destructive testing procedures:• Will NDT be performed and if so, what is the extent?• Will this be done:

- by the sub-contractor- by the company itself - by a testing company chosen by the sub-contractor- by the testing company used by the main company, which will also inspect the main

company's own manufacturing- for which authority shall the results be presented, and who will present them?

3) Heat-treatment procedures:• Is heat treatment needed?• Who will be the expert for heat treatment: The main company or the sub-contractor?

4) Qualification of welding procedures:• The sub-contractor's welding procedures shall be qualified by the method required by thequality requirements of the product to be manufactured

5) Qualification of personnel:• Are the qualifications of personnel adequate or does the sub-contractor’s personnel need

new qualifications for the product to be manufactured, eg, welders and welding operators?• Has a responsible welding co-ordinator been nominated and what is his task?• Is the responsible welding co-ordinator employed by the sub-contractor?

6) Material

• Does the main company deliver materials to the sub-contractor and how are theseidentified and separated from the subcontractor's own materials?• If the subcontractor buys the material, the following need to be specified:

- Type of material (e.g. standard, composition, dimensional tolerances, etc.).- Quality requirements for materials- Approvals, material certificates required

- Requirements for identification and traceability of the material7) Selection and identification of welders:

• Where necessary, the same level as applied by the main company

4.6.5 Sub-contracting of calibration

An assessment of the subcontractor will be performed during which the items listed in clause4.16 will be checked.

4.7 Welding and the associated personnel

4.7.1 General

The purpose of the procedure is to ensure that the company has the required competentpersonnel capable to fulfil the tasks required by the contract, by the regulatory requirements,and by codes and orders of other bodies concerned.

The procedures apply to qualification of personnel and their various tasks.

The responsibility for the skill of the personnel can, for example, be allocated to the company’sHR manager or production manager. In the welding matters, the responsible welding co-ordinator will be contacted.

At technical reviews, personnel required for various projects are discussed along with theirqualifications.

4.7.2 Welders and welding operators

Those doing welding work are required to be qualified according to the relevant part of ISO9606-1 or EN 287, ISO 14732 or EN 1418 unless otherwise required by the product standard








18

or in the contract. The procedures show how qualifications and possible renewal includingpossible special requirements are to be dealt with. In some cases, a production test on site isrequired before the welder can start to work.

The welder's job description could also include the following activities:• joint preparation (according to instructions)• fitting (according to instructions)• maintenance (according to instructions).

4.7.3 Welding coordinator

The company shall nominate at least one welding coordinator (responsible), who has the

overall welding responsibility and the necessary authorisations (e.g. to stop production). It ispossible for one responsible welding coordinator to be responsible for several sub-contractors.

If the field of activities of the company is broad, the tasks can be shared, e.g. between the leadwelding coordinator and other welding coordinators or welding foremen. Where necessary, thewelding coordinators and welding foremen report to the lead coordinator. The qualifications of the welding coordinators need to be demonstrated through sufficient experience or training(e.g. IIW).

• Heat treatment records• Non-conformance and corrective actions• Quality records

4.14 Inspection and testing

4.14.1 Contents

The purpose of the procedure (Inspection and Testing Plan) is mainly to ensure that qualitycontrol is in place before welding, during welding, and after welding.

Procedures are prepared for visual inspection and for both destructive and non-destructivetesting.

The overall responsibility for inspections lies with a person who is independent of production,e.g. the quality manager. The person or organisation performing the inspection is responsiblefor the actual inspection work and its results. The inspectors' visual acuity should be checked atregular intervals. The majority of inspections do not require an outside inspector, e.g. a weldertrained for inspection tasks can do the visual inspection of the welds he has made. The generalprinciple is that the person doing the work is responsible for that work.

4.14.2 Inspection and testing before welding

The procedure may include:a) Inspection of the welder’s qualifications:

• Validity• Suitability (range of qualification)

b) Welding procedure specifications/work instructions:• Necessity• Suitability• Correct welding procedure specification• Parent material and material thickness• Identity of parent material• Welding consumable(s) (marking, storage, and condition)• Dimensions of joint preparations (method of preparation, bevel angle, gap, depth of rootface)

• Test object• Extent of testing• Testing time• Test methods/equipment• Subcontracting• Test instructions• Testing conditions (e.g. lighting, viewing angle, viewing distance)• Acceptance levels (e.g. corresponding to quality levels)• Recording instructions or report forms.

4.14.5 Inspection and testing status

The inspection or test status of the welded structure is given in an appropriate manner, e.g. bymeans of a marking on the object itself or a traceability card.

4.15 Non-conformances and corrective actions

The purpose of procedures is to ensure that• a nonconforming product does not go forward into production, for use or to be delivered tothe customer• correction is taken to correct the nonconformance• corrective actions are taken to avoid repetition of the fault.

The procedures concern welding, inspection and non-conformances found after delivery. It isimportant to define what a non-conformance is.

All parties are obliged to report of any non-conformance they have noted. Depending on thenature of the non-conformance, the welder shall have the right, if necessary, to interrupt his/herwork.

A designated person shall be given the responsibility for ensuring that the corrections/repairsare made according to instructions and completed, and that the required quality has beenreached.

4.15.1 Procedures when the welding procedure specification has not been followed or is

impossible to follow

If the welding procedure specifications/work instruction was not followed, the welder shallinform e.g. the foreman/responsible welding coordinator about it. A non-conformance reportshall be made of this type of non-conformance.

The contents of the report should include e.g. of the following items:• Description of the non-conformance• Proposed action (correction of welding procedure specifications or work instructions?)• Decision• Control of implementation

• Corrective action. The procedure should describe how to proceed, e.g.








28

a) No actionb) Correction without permission

c) Correction with permission from a certain person

d) Classification for alternative use

e) Scrapping.

Any repair welding shall be done according to the qualified welding procedures.

4.15.2 Procedures for non-conformances found during inspection

during inspection:• The way in which the imperfection has to be marked• Acceptance of the non-conformance• Increasing the extent of testing and additional test methods (see, technical review)• corrective actions (see, technical review)• reporting (see 4.15.1).

4.15.3 Procedures for non-conformances found after delivery

Procedures for dealing with non-conformances found after delivery may include the following:

• Classification of the non-conformance

• NDT• Heat treatment• Does the welding procedure specification really meet the requirements for the work to bedone?• Has the welding procedure specification been wrongly prepared?• Has the welding procedure specification been qualified by previous welding experienceaccording EN ISO 15611 (the qualification of WPS to be withdrawn?)• What method has to be followed in corrective and preventive actions?• Reporting• Others

4.16 Calibration and validation of measuring, inspection and testing equipment The purpose of the procedures is to ensure that the measurement instruments and equipmentin use meet the required technical and other criteria for fulfilling the requirements specified bythe customer. Requirements for calibration and validation of equipment used for welding,including ancillary activities are given in ISO 17662.

The procedures refer to the measurement instruments and equipment used in manufacture andinspection.

The company shall nominate a person responsible for calibration and validation. The companyis responsible for the appropriate calibration or validation of inspection, measurement andtesting equipment for welded products. The extent and level of accuracy of the calibration orvalidation and the interval between these activities shall be defined by the company accordingto required product standards. It shall be observed that tight production tolerances cause agreater need for accuracy of calibrated or validated equipment. Generally, calibration concerns








29

instruments and equipment (master instruments) used for validation of instruments used intesting the final properties of a product. For products requiring great accuracy, the degree of measurement uncertainty (accuracy) shall be known and it is necessary to ensure thecompany’s own measurement equipment is traceable to international measurement standards.

The company shall prepare the necessary calibration or validation procedures for instrumentsand equipment. The most common objects of calibration or validation in the welding industryinclude:

a) The equipment required for inspection by measuring of finished products or, if necessary,parts, e.g.:

• measuring tapes for final inspections

• caliper gauges and micrometers• gauge blocks• dial indicators• angle gauges• measuring instruments for throat thicknesses• rulers• matrices• thickness gauges• theodolites and measuring machines

b) Gauges and meters used in welding and flame cutting, e.g.:• ammeters and voltmeters• tachometers• gas flow meters (rotameter)• wire feed regulator

c) measurement equipment required in heat treatment and pre-heating, e.g.:• plotters• regulators• thermoelements• thermometers• pyrometers

d) Equipment used in non-destructive testing, e.g.:• magnetization equipment• magnetic field gauge• light intensity meters• X-ray equipment• viewing devices• densitometers• ultrasonic equipment and calibration blocks

e) Destructive testing:• The equipment should be subject to official calibration inspection, e.g. hardness, tensiletesting machines and impact hammers.








30

4.17 Identification and traceability The purpose of the procedures is to ensure that the identification and traceability of the weldedproduct or its parts are maintained throughout the whole manufacturing process.

The procedures concern organizing and documenting the identification and traceability of welding and related activities.

The company is responsible for planning, managing and documenting identification andtraceability at the product level.

Identification and traceability relating to welding should include, if necessary, depending on thestructure and its application:

• identification of production plans (see also clause 4.10.1)• identification of routing cards or a list• identification of weld locations, e.g. by a drawing of the actual situation• identification of non-destructive testing procedures and personnel (for which object?)• identification of welding consumables, e.g. designation, trade name,, manufacturer of welding consumables and batch or cast number, if required• identification and/or traceability of parent material, e.g. type, cast number, if required• identification of location of weld repairs• identification of location of temporary attachments• traceability for fully mechanized or automatic welding units to specific welds• traceability of welders and welding operators to specific welds

• . traceability of welding procedure specifications to specific welds.

4.18 Quality records

4.18.1 General

The quality records are an essential part of the company’s quality assurance system. Theyprovide the basis for its quality policy, quality objectives and working methods and they ensurethe repeatability of procedures. With the help of the quality records and systematic workingmethods, it is possible to get customers and possible third parties, already interested at the firstcontact. At the same time they may also be convinced of the company’s ability to manufactureand deliver the required product.

The records should be used by all those whose work is affected by the document in question.

The quality records can be divided into two groups:

1) The documents relating to the company’s own activities e.g. operational and workinstructions for the organization, distribution of responsibilities and operations of the company.

2) Quality files derived from the documents, reports and check lists (forms) on actions relatingto the product and documents delivered to the customer together with the product.

4.18.2 Records relating to the company’s own operations

In a welding company records are, for example, the organizational description/chart,

responsibilities and authorizations within the organization, the equipment list and documentsspecified in ISO 3834-2.

These include instructions relating to document management and procedures for:








31

• how perform certain operations• references to standards, if possible• the person performing the operation• the timing of the operation• signing the completion of operation.

In addition to table 2 the following records may be useful:

• correspondence with the customer, inquiries, offers/tenders, orders, confirmations of orders• documents and confirmations of orders relating to purchasing• drawings• approved subcontractors• non-destructive and destructive testing procedures and reports• procedures for acceptance of parent materials and transfer of marks• material certificates

4.18.3 Quality files regarding a specific product

A contract, product standard or law may require that certain quality records have to bedelivered together with the product to the purchaser and in some cases also to the relevantauthorities.

Quality files should also be retained in order to demonstrate the achievement of the requiredquality and the efficient functioning of the quality procedures.

The documents should be prepared at the stage of manufacture or inspection concerned andcollected so that they can be collected immediately when the product has been completed. Thewelding coordinator or the person responsible for quality should check and approve thedocuments before sending them to the customer.

The documents should be sufficiently clear, accurate and easily identifiable as belonging to aspecific product, so that it can be proved afterwards that the requirements of manufacture andinspections have been fulfilled.

The manufacturer files the documents in accordance with its own archiving procedures.Another way of ensuring that the necessary documents are created on schedule is to have aproduction or quality plan covering the stages and operations involved in the product’smanufacture and inspection, signed by the responsible person when the required actions havebeen completed.

The documents specified in the contract shall be submitted together with the product. Thedocuments to be delivered may include the following:

• records of requirement/technical reviews• production/quality plan• material certificates

• information on welding consumables• reports of material testing• routing cards relating to inspection








32

• measurement and other test reports• list of welding procedure specifications used• list of qualified welders used• heat treatment procedure specifications and reports• records of repairs and non-conformance reports.

The periods for retention of individual records shall be defined and documented and the

record holders identified.

4.18.4 Document management

The manufacturer should create an easily usable list-based or other equivalent procedure for

document control, in order to verify their validity and to prevent the use of invalid and/oroutdated documents.

The documents shall be provided with an identification number, a revision number, signatureand date of approval. The persons to whom the documents have been delivered to shall belisted, and at the same time it is ensured that all have the latest revised version at theirdisposal. The documents may be filed as a hard copy or in an electronic format, for example for10 years. The person who has approved the original document should also approve anychanges made. The points changed are to be marked in a suitable manner.

5 Need for certif ication

Fulfillment of the requirements of ISO 3834 can be demonstrated in different ways. Often the requirement may bea certification of the system. The company should be able to choose itself whether it wants certification to promotemarketing, to improve overall quality and efficiency and to increase the credibility of its operations from thecustomers’ or stakeholders’ perspective.

There are several ways of showing the customer or a potential customer that the company’swelding quality requirements have been met. These are:

• a method bilaterally agreed on between the customer and the company• auditing by the customer• auditing by a third party chosen by the customer.

Quality is always a question of agreement between the customer and the supplier, which doesnot necessarily require certification.

6 Adoption of ISO 3834 in a company

The adoption of ISO 3834 in a company may, for example, be carried out in as a project inthree stages.

AT the fi rst stage the company has to carry out a survey of the current situation. This stage

should be performed with great care and sufficient time should be spent on it, as it forms thebasis for the success of the whole project. The current situation should be examined asthoroughly and as truthfully as possible. It is human at this stage to “embellish” the actual








33

situation in the company. Such embellishment, however, makes the actual advantage gainedfrom the project smaller than expected. Very often only the requirements of the standard will bemet, but the possibilities for improving the quality and efficiency of the production will be lostalready at the beginning of the project.

In many cases the examination of the initial situation is useful, if consultation with an outsideexpert is used, because the expert has no need to describe the situation as better than itactually is. Neither is an outside expert subject to “workplace blindness”, which is only humanfor people who have worked for a long time at the same workplace.

When real quality improvement is defined as the goal, it is important to gain the commitment of personnel at all levels in the company’s hierarchy to the project. The executive management of

the company shall give and demonstrate its full support for the project from the beginning to theend. This is supported by informing and training the personnel at the earliest possible stage.

It has been found useful to arrange training of the stuff in connection with the survey of thecurrent situation. The number of company’s staff, products and company culture are importantfactors making the organizing of a training event beneficial. Separate training events can beorganized for clerical staff and welding personnel, or all personnel groups can be gatheredtogether in one event. The advantage of the first alternative is that the content of the trainingcan be tailored accurately to meet the needs of target group. For example, for welders, theitems of the standard on “Equipment”, “Welding activities” and “Welding consumables” can behighlighted. For the clerical staff it would be useful to concentrate, for example, the item“Requirement and technical reviews”.

The advantage of a common training event organized for the whole personnel would be that itwould be possible to examine matters from different perspectives. The various personnelgroups would gain an overall picture of all the operations affecting quality management inwelding as required by the standard. The personnel groups would get knowledge of items dealtwith in other groups’ areas of responsibility and understand the actions required by themselvesand others and the linkages and dependencies between them.

The number of participants in the training events should be restricted to enable an open andcontrolled discussion of matters. In large enterprises it is better to arrange several events thanto bring together the whole personnel or personnel group in one training event. There is no

reason to underestimate the importance of training or information events, because the basicrequirement for a successful project is that the whole personnel is involved in developing theactivities.

The main objective of the first stage is to identify and record items needing improvement. Afterthis stage it is often useful to update the project plan, in order to ensure a realistic schedule forimplementation.

At the second stage, on the basis of the initial survey, an action plan shall be prepared foraddressing the items needing development and the planned actions shall be performed. Theseactions may be split into separate tasks, for example, according to the list of contents in thestandard or to the companies own quality manual. Chronologically the separate tasks may be

carried out either simultaneously or successively. The method of implementation depends onthe resources available for the project and how responsibilities are assigned in the company. Atlatest at this stage of the project, it is recommended to nominate a responsible person(s) foreach item to be developed.








34

Training of the company’s personnel continues at this stage. While the first stage mainly givesinformation on the content of ISO 3834 and the actions regarding needed procedures anddocumentation to meet the requirements, at this stage the objective is focused on the technicalcontent of actions and procedures. Activities and training given at this stage are to a largeextent decisive as regards the technical and economic benefits that adopting ISO 3834 willbring the company.

When the items according to ISO 3834 are used as a tool for measuring the quality producingcapacity of the company, and the weaknesses and disadvantages found as a result of usingthe standard are addressed properly, the productivity of welding can be improved and qualitycosts cut, so that the expenditure and effort put into the ISO 3834 project will be found as anexcellent investment.

The duration of the second stage depends very much on the size and initial situation of thecompany. If the company has a certified ISO 9001 quality system in place and it has, forexample, successfully manufactured standardized products, it has in practice already had tooperate according to many of the items of ISO 3834-2. Readiness for certification can in thiscase be achieved quite quickly and with a very reasonable amount of work. The additional workmay be limited to revising of a few operational procedures to bring them into the form requiredby ISO 3834.

The work is considerably more demanding if the company does not have a certified qualitysystem, or a well documented quality management system has not been required for theproducts it manufactures, especially as regards welding. The work of preparing procedures is inany case quite extensive even though an effort is made to minimize the number of proceduresto what is appropriate. Time and resources shall also be reserved for understanding thepurpose of the procedures and for learning the tasks involved in practice and establishing themon all levels of production.

Typically, 6–18 months shall be reserved for the second stage. In order to achieve a timetableof 6 months, the ISO 3834 work shall be done by teams of several (> 3) people simultaneouslyin the different areas of operations. If the implementation of the standard will be done in ateam, as small as possible, (e.g. in addition to normal workload), the project will easily takemore than a year.

The estimates above mainly concern companies with a wide production program. If thecompany manufactures a clearly limited range of products, where the welding work is similar,and the requirements are clearly established, the timetable for adopting ISO 3834 may bemuch shorter.

The third stage involves checking the functional effectiveness of the quality managementsystem for welding and its compliance with standards, so that any remaining disadvantages arefound before the real audit by an external party. This “pre-audit” could be carried out by anexpert in the project, who has not participated in developing the procedures of the companyconcerned. The pre-audit could also be done by an outside expert familiar with ISO 3834. Theidea here is to avoid a situation where a person could assess the results of his or her ownwork. Any disadvantages found will, of course, be corrected, after which the company can ask

for an audit by an accredited certificating body. The end goal is an effectively functioningquality management system for welding, and at this stage all the procedures will comply withthe appropriate requirements according to ISO 3834.








35

Problems The most common problems occurring with the implementation of ISO 3834 are:

• purchasing or ordering

• status of the responsible welding coordinator in the company

• handling of welding consumables

• following the welding procedure specifications

• validation of ammeters and voltmeters

• range of qualifications.

Annex B: Example of a simple procedure for quali ficat ion of welders Scope

This procedure ensures that the welders have the required qualification

Field of application

This procedure concerns qualification of welders according to ISO 9606/EN 287-1.

Qualification testing of welders and examination

All welders perform qualification tests according to ISO 9606/EN 287-1. Annex A includes a list of the qualification

tests to be performed. For examination check list C 6.2 will be used.

Testing

The welding co-ordinator performs the visual testing according to ISO 17637. After acceptance the test pieces will besent to testing laboratory (Inspection Ltd) for radiographic testing. (see procedure B 5.3j).

Quality records

The responsible welding co-ordinator files a data base including all welders' certificates. The data base includes a listof welders, their qualification and validity.

Validity

The welding co-ordinator signs the certificates every six months. For signing the welding foreman provides the weldingco-ordinator with all necessary information concerning welding work. Every two years new qualification tests arecarried out.
