Stellite 6 overlay on 316SS, TIG Process

What is the best Gas to use when doing a stellite overlay on 316SS?
Thanks

Argon is fine...and is probably the best choice.

an oversized tig cup will help things go better.

Stellite 6 welds pretty clean unless it gets oxidized and then the puddle gets sluggish...and that usually makes the welder go hotter to make the puddle flow.

keeping it really clean every pass by shielding with an oversized tig cup and argon gas, will help all passes to flow easier.

this is what I am talking about
