Welding with argon helium mixtures
Welding with argon helium mixtures
(OP)
What would be the purpose for welding stainless and nickel alloys with an argon helium mixture for shielding gas. And would it be ok to weld 300 series stainless steels with this mixture?

In some application argon alone is used to weld austentic stainless steel while an Argon/Helium mixture is used on the ferritic and martensitic grades.
