Best TIG Welders For Stainless Steel

TIG welding is a process which uses a non-consumable tungsten electrode which delivers a current to a welding arc while the weld puddle and tungsten are cooled and protected by an inert gas which is usually argon but it could also be a number of other inert gases.

Quite similar to oxy-acetylene welding, TIG welding is sometimes known as Heli-Arc welding and as it uses an inert gas it prevents oxidisation during the weld which stops any defects it produces a very clean and even weld which is desirable when performing aluminum or stainless steel welding.

This is the preferred method for carrying out dairy grade welding and it is also widely used in the automotive industry. TIG welding also offers another advantage in that the user has better visibility of the project in hand and so can achieve greater precision and accuracy.
