Aluminium alloys AA2024 and AA7075 plates were friction stir welded by varying the tool rotation speed and welding speed and corresponding tensile strength of the joints were measured. A mathematical model was developed using response surface methodology to predict the tensile strength of the joints. The FSW process parameters were optimized for maximizing the tensile strength using particle swarm optimization algorithm. The optimum FSW process parameters for dissimilar welding of AA2024 and AA7075 plates were deduced as welding speed of 15 mm/min and tool rotation speed of 1087 rpm. © 2018 Elsevier Ltd.
