Best Gas For Stainless Steel Tig Welding. TIG Welding Stainless Steel involves the use of a tungsten electrode to produce a weld. Gas-tungsten arc welding GTAW also known as tungsten inert gas or TIG welding is a joining process for stainless steel.
The gas that most welders use for TIG weld on steel is Argon. Gas-tungsten arc welding GTAW also known as tungsten inert gas or TIG welding is a joining process for stainless steel. Nitrogen works as a purge gas on the backside of a TIG weld because it isnt exposed to high arc temperatures.

In some cases there is tri-mix shielding gas containing 90 Helium 75 Argon and 25Carbon dioxide. However as the thickness of the material increases. The gas contains an active component H 2 which brings down the oxygen level in the weld area. 08 The right gas mixtures for TIG and plasma welding Argon 46 Argon is the simplest gas for TIG welding stainless steels and nickel alloys.
