TIG welding is another name for gas tungsten arc welding. The aircraft industry created it to weld magnesium in the 1930s and 1940s. Ideally the process works like this: the welder makes an arc between the base metal and the non-consumable tungsten electrode, a type of electrode that does not melt. At the point where the arc hits the base metal ...
