Course overview

Tungsten inert gas (TIG welding, also known as gas tungsten inert welding (GTAW), is used to weld thin section of stainless steel and metals such as magnesium, aluminum, and copper alloys. The TIG welding process gives the welder greater control over methods like shielded metal arc welding and gas metal arc welding.

The Tungsten Inert Gas (TIG) Welding training course introduces the procedures and equipment used in this welding. It also discusses the design and function of components used in the processes. This online course includes:

  • Principles of TIG welding
  • TIG welding equipment
  • TIG welding procedures

Tungsten Inert Gas Welding is part of the Welding and Cutting for Maintenance training series.
