Regard to ASME IX, A PQR is qualified to piping, so could it qualified to plate ? Many thank
Yes, WPS may be qualified on plate.
Your question answered topic Supplementary essential QW-405.2 welding positions deleted in ASME IX 2019
Should be ok.
If other welding variables are unchanged, this WPS can cover material SA516 Gr. 70.
You can develop a new WPS.
