From your query I presume You want to weld P5A claded plate to SS316L plate.
You require to qualify PQR i) Butt weld of SS 316L to P5A i.e. P8 to P5a using NiCrMo3 with require PWHT as per code UCS 56
ii) option2 Butter the P 5A with NiCrMo3 carry out the PWHT as per code later weld with the same with P8 to buttered P5A but w/o PWHT This will be job specific PQR
Hope there is no clad restoration on SS portion
You have to qualify the procedure as the same configuration of production. For cladded and buttered configuration you have to make the same test coupon and weld. You have to confiy the chemistry also at the root.

I have one query regarding welding qualification of cladded base metal. Our first base metal is Stainless steel 316L to weld with second base metal P5A cladded with Stainless steel 316L. A layer of ENiCrMo-3 was buttered on bevel of second base metal by other. As i know a layer of ENiCrMo-3 act as barrier layer. The problem is how to qualify the welding procedure on stainless steel 316L to P5A cladded with Stainless steel 316L. Is it i need to qualify P5A cladded with Stainless steel 316L or Stainless steel 316L to inconel ENiCrMo-3 or Stainless steel 316L to Stainless steel 316L procedure. I really need your advice and expertise. What is the best practice or code requirement on qualification of cladded base metal. Advance thank for your kind cooperation and really appreciated
