ASME SECTION IX-WELDER QUALIFICATION

pls. help me asap
Thanks
M.B.S

RE: ASME SECTION IX-WELDER QUALIFICATION

There is nothing in ASME Section IX that specifically states an Authorized Inspector must be present during qualification of welders or procedures. All that is required is someone (could be an AI, or Weld Supervisor or QC Inspector) be present to witness that the welder has completed the coupon in accordance with the required WPS – see QW-301.2 in ASME Section IX.

An Inspector (AI) always has the right to witness any aspect of weld procedure qualification, welder performance testing, and witnessing production welds during fabrication.


IF at any time, the Inspector questions the ability of a welder to produce quality welds during production, the Inspector can request that welder re-test or revoke their certification for the welding process in question until re-testing. IF the Inspector witnesses the welder performance qualification and the weld is not visually acceptable, the welder can be forced to re-test. Re-testing is described in QW-321 in ASME Section IX.

Thanks for reply.....
Also is there any limit that welder can re-test to qualify?
Also if welder fail in first test due to not full penetration at only 5% portion of 2-1/2" coupan, than is he require any training before go for re-test?
Our A.I inspector asked this.
Pls...let me know.

RE: ASME SECTION IX-WELDER QUALIFICATION

Agree with Metengr, however, be aware that requirements can vary between jurisdictions.  When I was working in Ontario, the AI did witness the welding of every PQR and WPQ.  He would come in and stamp his symbol on every coupon, look at at the root pass, the final weld, and return to look at the coupons.  He always looked for his symbol on the tested coupon.  That was 15 years ago, maybe thigs have changed?

RE: ASME SECTION IX-WELDER QUALIFICATION

QW 321 in ASME Sec IX details the procedure for retesting welders.  The manufacturer decides when retraining is required.
Basically the Code says if a welder fails a test, and is retested immediately, ie without further training, he is retested on twice the number of test plates and  must pass them all.  
If he receives further training, he is retested in the normal fashion.

RE: ASME SECTION IX-WELDER QUALIFICATION


1- Your quality procedure should cover the requirement since it is not in the Code

2- real simple: re-train your welder or hire a welder
who will pass

mihir5577,
It appears that your welder performed poorly. For the life of me, I cannot understand the propensity of employers to want to hire welders who cannot pass the qualification tests by giving them more and more chances at qualification or leeway in qualifcation. If a welder has difficulty passing a test in near ideal conditions, what will he do in production in potentially highly non-ideal conditions?
