Filler material chemistry will have variation with welded chemistry.
SS filler meal will have additional Cr & Ni to compensate evaporation losses
during welding. Hence welding to be carried out using particular filler metal
and it's chemistry to be analysed as per code.
You have to follow ASME sec. II part C and respective classification. For example
SS filler wire comes under SFA 5.9. GMAW filler metal specified under SFA. 5.18
and like wise.
