Gas Mix For Tig Welding Stainless Steel. TIG welding works in the presence of inert gases. GAS FOR TIG WELDING.
Gases for all types of stainless steels The right gas mixtures for TIG and plasma welding VARIGON He30 This argon and helium gas mixture is suitable for TIG welding all grades of stainless steel. It produces a stable welding arc and is suitable for all grades of stainless steel. TIG welding works in the presence of inert gases.
Nitrogen works as a purge gas on the backside of a TIG weld because it isnt exposed to high arc temperatures.
Helium He can be added to increase penetration and fluidity of the weld pool. The inert gas belongs to the working situation and the base metal on which the welding works proceeding Mostly the argon and helium gases are used because as per function and inert gas protects the welding area against the environmental particles. In some cases nitrogen N 2 andor hydrogen H 2 can be added to achieve special properties. Ad China Sale Welding Machine.
