Diagram shows how the TIG welding process works. TIG is short for Tungsten Inert Gas and it is a common type of welding for used for stainless steel aluminum titanium and other non-ferrous metals. In this welding a non-consumable electrode is used which does not melt. The supplied current form a spark between the tungsten electrode and the workpiece.
