Gas Tungsten Arc Welding (GTAW) is one of the most popular welding techniques for aluminium alloys. The accuracy and efficiency of the joint largely depends upon the type of power supply(DCEP/DCEN/AC), welding speed, type of shielding gas used. This paper deals with the review of various parameters on which weld quality depends and researches carried out to analyze the weld quality obtained, defects encountered, effects of welding parameters on weld bead profile and mechanical properties etc. for TIG welding of aluminium or aluminium alloys. It consists of the amalgamation of effects of various parameters and the techniques suggested and adopted for their optimization to obtain a better-quality joint with reduced crack sensitivity, improved mechanical strengths and stronger Heat Affected Zone (HAZ).
