Friction stir welding (FSW) is a recent method for welding in solid-state environments. The FS welding parameters, namely pin rotation speed, welding speed, axial force, and tool tilt angle affect weld joint microstructure and tensile strength. The study optimizes process settings to enhance mechanical properties and uses Response surface methodology (RSM) to predict the ultimate tensile strength (UTS) of FS-welded AA 2024-T6 and AA 5083-H111.These parameters must be understood to get optimal mechanical qualities in manufacturing. The created model predicted tensile strength within 5% of experimental data, helping optimize process parameters for FS welded joints. Tool tilt angle affects heat, material flow, defect generation, welding force, and friction stir weld joint quality.
