4 TIG WELDING

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, 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.
