Newbee here!!!
My shop is asking if they can pick and choose welding process from multiple WPS.
To make more clear, we have one set of PQR and WPS with Tig and FCAW process and another set of PQR and WPS with Sub arc. The essential variable are not changed.
Can they use these two sets to do all tig, fcaw, and saw?
PS. Under ASME pressure piping code.
