Re: [MW:18851] Welder Qualification for Hot-Tapping

Your welders were already qualified in GTAW + SMAW.

1)  Now just verify the dia in which your welders were qualified,(his qualification range is covering 2"dia )

2)  As welders were qualified in ,Multi process , verifiy the SMAW thickness range of their qualification. whether it is matching with your job requirement.

If above 2 points were matching there is no need of qualifying again, if not you have to qualify them again to meet the Code requirements.

Dear Experts, 

We have a Hot-tapping Job of 2" set-on branch on 42" & 24" Run pipe. Code of construction is B31.3 AND material is SS 321. But our welders are ONLY qualified in GTAW+SMAW. So We need to prepare new WPS and conduct PQR, but my doubt is it mandatory to qualify the welders in SMAW on 2" pipe for this job.Please advise.

Thanks & Regards

LALU R.P
