Annex A

(informative)

Recommendations for technical knowledge in welding

The International Institute of Welding (IIW) has, on a voluntary basis, prepared recommendations

for minimum requirements for education, examination and qualification of welding coordination

personnel.

The recommendations are stated in the following documents:⎯ International Welding Engineer (IWE),

Doc. IAB-252;

⎯ International Welding Technologist (IWT),

Doc. IAB-252;

⎯ International Welding Specialist (IWS),

Doc. IAB-252.

Welding coordination personnel fulfilling the requirements of these documents, or holding

acceptable national qualifications, may be considered to satisfy the relevant requirements of 6.2.

EWF addition to the system

European addition to the

education for Welding

Coordinator is here!

• EWF introduced a

supplementary Europeaneducation scheme, meant

especially for the SME in

steel construction work.

•

B and S levels; EXC 2 and 3,up to and including S355.

Th W ldi C di (EN ISO 14731)


15/28


So: the Welding Coordinator in three levels: – comprehensive technical knowledge

– specific technical knowledge

– basic technical knowledge

• Sometimes there might be a requirement

for a certified Welding Coordinator.

• Can/may be more than one person.

• Always ONE responsible: the “RWC”!

Qualification of a Welding Coordinator


19/28

Qualification of a Welding Coordinator

Lots of questions:• Does the RWC have sufficient experience in the welding operations he supervise

as specified in EN-ISO 14731?

• Does the RWC have a suitable role, with given responsibilities to coordinate the

welding operations, defined by the manufacturer? (See EN-ISO 14731, Annex B.)

• Does the technical discussion with the RWC demonstrate that he has sufficientknowledge about relevant standards, regulations and specifications as per

EN 1090-2, clause 7.4.3 and EN-ISO 14731, Annex B?

• Does the RWC have the ability to detect and assess defects, to give instructions

on welding repairs and know how to avoid defects?

•

Does the RWC have relevant technical knowledge complying with one of the IIWqualifications?

• Etc.

But how to implement??

Qualification of a Welding Coordinator (EWF/IIW)


20/28


European Accreditation is quite clear in EA-6/02:2013Special attention for the Audit Team in evaluating the competence of the

manufacturer’s Welding Coordinators in accordance with

EN ISO 14731 (reference 6).

The EN ISO 3834 Audit Team shall:

i. contain persons with direct product/process/materials competence in the

products/processes/materials being audited, and

ii. contain at least one individual who is qualified and experienced in welding to

a level that is sufficient to demonstrate that he/she is competent to Audit the

company’s Authorised Welding Coordinator(s) in accordance withEN ISO 14731, ‘Welding Coordination – tasks and responsibilities’

(reference 6).

Situation

Additional requirement

Activity required towards the (R)WC EWF/IIW qualification is

available (E/IWE, E/IWT,

E/IWS)

“Type 1”

None Check on adequate experience and

competence in the products being

manufactured by means of a professional

interview and examination of the Welding

Coordinator’s curriculum vitae.

EWF/IIW Personnel

Certification is available

(CE/IWE, CE/IWT,

CE/IWS)

“Type 1”

Schedule should

support the scope of

work allocated to the

Welding Coordinator

Check on adequate experience and

competence in the products being

manufactured by means of a professional

interview.

If none of the above

EWF/IIW certifications or

qualifications areavailable

“Type 2”

None Verify compliance by means of a professional

interview covering knowledge, skills,

experience and competence with particularemphasis on welding technology, materials

and their behaviour during welding, design

fundamentals of welded construction, as well

as fabrication and inspection aspects

(including knowledge of standards) in the



22/28


The professional interview process shall involve theexamination of specific contract(s) to Audit

compliance with the customer’s specification

E.g. in the following areas: – selection/development of welding procedures

– welding sequences

– NDT and heat treatment

– approval of personnel

–

traceability – quality control and acceptance

– sub-contracting



23/28


This means that technical discussions must take placebetween each Welding Coordinator and the relevant

Auditor regarding the detailed technical scope of the

Welding Coordinator's responsibilities and the interview

should take the form of a peer review and challengeprocess. This process will require the Auditor to examine

evidence of completed work done by each Welding

Coordinator and to investigate his/her knowledge and

understanding of it. The certification body shall maintainfull records of the process of evaluation of the

manufacturer’s Welding Coordinators.



24/28


Basically we can see two essentially different professionalinterviews (see table in sheet 21):

1. Checking the actual knowledge related to the

manufactured products to be covered by the Welding

Coordinator.

2. As specified in 1, but additionally covering knowledge,

skills, experience and competence in the fields that are

supposed to be covered by EWF/IIW qualifications and

certifications.



25/28


That means:

General knowledge and skill check for the (R)WC:

• Challenge the (R)WC by asking questions of the “what-if” type;

• Try to cover his/hers whole scope of work.

Additional knowledge and skill check for the (R)WC:

Type 1:

• Select a running (just delivered) contract and follow every single step as related

to the (Responsible) Welding Coordinator;

Type 2:

•

As under 1, but in addition select random questions out of the questionsdatabase for EWF Guideline 652 or IAB 252 and use them as a guidance for the

Professional Interview Type 2. All relevant modules shall be covered!

7. Questions for discussion


27/28

Questions for discussion for the professional interview (EWF/IIW)


28/28

Q p ( / )

Questions for discussion:

1. The system looks quite subjective; is there another way?

2. Should a minimum time be allocated to the professional Interview?

3. Should a “technical shop-tour” be an essential element in the

interview? (Note: that’s not always possible!)

4. Should EWF/IIW make a detailed check list for the professional

interview as specified in the Rules EWF 639r2-12 and

IAB 340r2-12?

5. Shall the evaluation be carried out on the RWC only or should it also

involve the other WC’s as mentioned in the company’s WC matrix? The group will be divided in 4 sub-groups; two groups will deal with

questions 1 and 2, the other two groups with questions 3, 4 and 5.
