[MW:11924] Welding Process Restriction

 

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
