Dear Mr.Bathula Raghuram
thank you for reply.

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
