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 & RegardsLALU R.P
