Role Of Inert Gas In Tig Welding. An inert gas does not react with the molten weld at all while an active gas participates in the welding process by stabilising the arc and securing the smooth transfer of material to the weld. Its very useful for welding aluminum and can be tailored for stainless steel as well.

We will discuss this later on the Shielding gas section. Since pure helium creates an erratic arc it can result in spatter when working with steel. The shielding gas can be inert or active.

The shielding gas can be inert or active.

It creates a more concentrated arc flame with higher heat inputs. TIG has played a major role in the acceptance of aluminium for high quality welding. An example of an inert gas is argon which does. Its very useful for welding aluminum and can be tailored for stainless steel as well.
