Experimental investigation of friction stir welding on aluminium AA6063

Abstract Friction Stir Welding, at which relative motion between the specimen and tool generates heat, as a result of which the edges are connected. Because of its excellent properties including very strong resistance to corrosion, weldability, and high fatigue strength, aluminum alloy is used in aerospace applications. Experiments were carried out on Aluminum alloy AA6063 and AA6201 in a Vertical CNC Machine. The performance parameters were calculated and the results indicate a definite relationship with the strength in tension as well as process parameters. For a selection of desired process parameters, friction stir welding process variable database is, therefore, to be created. ANOVA test found the most important process parameter which affects the strength in tension.
