Abstract: Fusion welding of aluminium alloys results in solidification cracking, porosity etc. which affects the properties of the weldment. FSW which is broadly used in welding of aluminium alloys. It overcomes the defects of fusion welding process in improving the properties of the joints. The current paper focus on studying the tensile properties of the disparate FSW of aluminium alloys AA6082 and A319 .Three dissimilar tool profiles (square, hexagonal and cylindrical) with three welding speeds (25, 30, 35 mm/min) and three tool rotational speeds (800, 1000 and 1300 rpm) have been used in studying the joint properties of the weld. Higher tensile strength was obtained for the parameters of square tool profile, 30 mm/min and 1300 rpm.
