Abstract: GTAW well known as tungsten inert gas welding (TIG) commonly used to join thin sections of non-ferrous metals like magnesium, copper and aluminium alloys. Allowing for stronger, higher quality welds the welding operator need great control on welding process. Because of short arc length, contact gap of filler electrode have to be maintain in a even way to maintain equal speed and depositing methods. Present work focuses on the TIG welding process and microstructure analysis of flaws in welding; also evaluate the mechanical properties of welded joints. The samples prepared as per ASTM weld samples, the extracted samples tested for microstructure, penetration and other mechanical tests. The results are showing good at the area of weld.
