AISI 321 SS, weld rod selection

(OP)
Could someone confirm the correct weld rod selection for the welding together of AISI 321 SS clad (10 mm thick)

RE: AISI 321 SS, weld rod selection

More information is needed.
Could you explain your joint detail and application?

RE: AISI 321 SS, weld rod selection

Standard filler wire selection for plain 321 SS is 347.
However if you have stainless clad on carbon steel you need a complex procedure.
Weld first the carbon steel side without penetrating the stainless cladding.
Backgouge the carbon steel and butter the carbon steel surface of the joint with 309 or 312 filler metal.
Fill the gap with 347.
