Abstract
GTAW (Gas Tungsten Arc Welding) or TIG (Tungsten Inert Gas) Welding is one of prime welding process which plays a vital role in most of the fabrication industries to weld various metals grades with various parameters. This TIG welding is most preferred because of the better joint which is produced during the process. Recent days new hybrid TIG like pulsed TIG, pulsed synergic TIG etc, comes into practice based on the applications. These TIG Welding variations comes into play because it increases the quality of weld furthermore by changing the various parameters like background current, voltage and control the heat that is generated over the process. In this paper, Pulse TIG is discussed to create an overall idea.[1] Babu, N. K., Raman, S. G. S., 2006.
