Hello all,
I am trying to develop my first clad PQR. The base material is, ASTM A516-70N. I then cladded this plate with inconel 625. We then prepared the plate for a single vee bevel and welded the butt, using ERNiCrMo-3 GTAW wire.
My question is: on the WPS what P member will the bas material come under, same as A516-70 P 1 Group 2 or do I state P1 / P43 ??
Second question: If base material is 12mm + 3mm of cladding, is my qualified thickness range 5mm to 24mm or 7.5mm to 30mm - is the cladding thickness included in the qualified thinness range?
all this is to ASME IX. thank you all very much
