4 TIG WELDING
4.1 Overview
TIG welding uses a non-melting tungsten electrode from which the arc is struck that melts
the workpiece. The molten weld pool and the tungsten electrode are protected by a shielding
gas.
Pulsing is used in order to give better control of the weld pool and solidification. The pulse
frequency is sufficiently low to allow some of the weld pool to start to solidify between each
pulse. Pulsing has four controllable parameters: pulse duration, background current time,
pulse current and background current.
