Dear all,

Provided a welder was certificated according to ASME BPVC Section IX in company A, but now he want to work in company B(different company from A, but both of two companys are in charge of products in compliance with ASME Code) as a ASME welder.

Do he need to conduct performance qualification according to Section IX again? Or alternatively, is there any choice for him to avoid the requalification?

Thanks very much.

Allen.

Yes Allen, he will have to requalify.

Yes he would need to requalify as per ASME Sec IX QW-300.2.

A welder takes a performance test and qualifies to that particular company's qualified procedure.

The only way a welder may not need to requalify is QW-300.2 (c) "If in an organization effective operational contol of the welder performance qualification for two or more companies of different names exists, the companies involved shall describe in the Quality Control system, the operational control of performance qualifications. In this case requalifiction of welders and welding operators within the companies of such an organiztion will not be required, provided all other requirements of SectionIX are met."

If you are performing work to ASME code as dictated in a contract then you must have a QA/QC Manual that states how you will control tests, materials, etc.

Sooeey2u,

Thank you for your direction, but I have three questions to QW-300.2(C) as you quoted as above.

No.1, What is the relation between the organization and two or more companies described here accroding to your understanding, and also that between these two or more companies? Or are all three parts independent?

No.2, What does the words "effective operational contol " mean?

No.3, How do two or more companies operate "describe in the Quality Control system, the operational control of performance qualifications"?

Allenliao,

This paragraph is usually used in sister-companies having a common corporate Quality system, where the welder qualification is made commonly and the welding engineer is in common.

If you have two really separate companies, the welder shall be qualified under both their systems separately. Considering the Manufacturer's reaponsibility, it is a good advice not to trust another company.
I have seen too many WPQ where the welder was not qualified properly, the RT was done wrong, the number of bends not acceptable, etc. On field sites, issue the gate pass only to welders who passed the test welding.
A WPQ test is not so expensive. A leaking boiler is.

Mr. DK,

Thank you for your interpretation. We have employed three welders from anther copany(different from us) with ASME welder certificates under qualification of that company.

The reason we employed them is that they can deposit good weld visually, but they failed to pass the RT test time and again. It is really a bottleneck.

Allen,
If the welders were qualified by another company then their qualifications are only valid for that company.
The work they are performing for you is subsequently being performed by unqualified welders,

Ballbearing,

Thanks. It means that I must insist these welders can only be used unless they pass the test, no otherwise approved.

Allen
