[MW:34597] Dissimilar welding chemical/PMI acceptance criteria

Dear Experts, 
Please provide reference of CODE, for chemical analysis acceptance of dissimilar welding. Here Alloy 825 welding by ERNiCrMo-3, 
Ideally weld metal should match ERNiCrMo-3, But can we accept Alloy 825 chemistry in weld metal.

Welding Process: EFW
Design Code: ASME Sec VIII Div.1
Welded part: Pipe Long Seam ASTM B474.
