[MW:4533] RE: 4531] qualified range for base metal

you can't, refer QW424.

Your PQR qualified on P1 to P43, where as you need to weld P1 to P1 which is cladded with P43

Dear All

i have a qualified wps that X65 WELDED WITH INCONEL 625.  

I think it can be used for welding of clad materials, but my owner have opposite idea.

according ASME IX (wich paragraph) it is clarified? (clad pipe consisted from inconel 625 & X65)

regards
