Working with thin forms of metals such as stainless steel or aluminum can present its own set of difficulties. Thanks to the development of tungsten inert gas welding (TIG), these obstacles have been overcome.
Additionally known as gas tungsten arc welding (GTAW), this technique of welding uses a non-consumable electrode composed of tungsten to complete a weld.
A TIG welder also uses a gas (usually argon) to protect the weld from contamination and in most welds, a filler material is also required. While this form of welding is favored to weld thin materials, it is also an extremely complex skill to master.
