Expert,
I have a 2 WPS qualified range as below:
1) WPS A – Qualified Thickness Range from 1.6mm – 11.08mm ; diameter range is all diameter. (Gtaw process)
2) WPS B – Qualified Thickness Range from 4.8mm – 22.0mm ; diameter range is all diameter. (Gtaw + Smaw process)
Both are qualified under ASME IX and for material with P No.1
Now, I need to weld a A106 GrB pipe 4" Sch40, can I use WPS A? Full Gtaw for 4" pipe? Any restriction for welding process pertaining diameter as in ASME IX?
Please Advice.
Thanks
