GTAW offers several advantages like joining of dissimilar metals, absence of slag, low heat affected zone etc. Gas Tungsten Arc Welding is an electric arc welding process, in which the fusion energy is produced by an electric arc burning between the work piece and the tungsten electrode. During the welding process the electrode, the arc and the weld pool are protected against the damaging effects of the atmospheric air by an inert shielding gas. By means of a gas nozzle the shielding gas is lead to the welding zone where it replaces the atmospheric air. The welding parameters are selected based on experience or from a handbook by operator. However, this does not ensure that the selected welding process parameters can produce the optimal or near optimal weld metal properties for that environment a particular welding machine. The aim of this paper is to effect on mechanical and metallurgical properties of dissimilar metal (304 stainless steel and CP-copper) weld byRead More
