This research investigates the influence of tool profile and rotational speed on the structural and thermal behavior of dissimilar weldments of Aluminum 7475 and Copper using Friction Stir Welding (FSW). Three distinct tool profiles (Round, Hexagonal, and Taper Threaded) were evaluated at varying rotational speeds (700, 1000, and 1400 RPM). Finite Element Analysis (FEA) was performed to simulate static and thermal responses of the welds. Results reveal that the Taper Threaded profile, especially at lower speeds, offers optimal thermal regulation, minimizing deformation and residual stress. This study provides insights for enhancing weld quality in dissimilar material joints.
