TIG stands for tungsten inert gas welding. In this welding process, you will use a tungsten electrode to create an arc that heats up metal to its melting point. The operator must press the foot pedal so that an arc is developed between the tungsten electrode and the workpiece. This melts the filler material, which then creates a weld pool on the workpiece. A weld joint is created when the weld pool solidifies after cooling.
