Dear Mr.Bathula Raghuram

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
