ResumoIn this work, optimization of the parameters of Friction Stir Welding (FSW) in unlike alloys using Taguchi-based Grey relational analysis was evaluated for aluminum alloys AA5083 and AA6061 under different parameters like rotational speed, feed and force with three levels each on tensile strength, elongation and hardness. Taguchi related experiments were performed using L9 Orthogonal Array. The grey relational grade is observed which correlates betwixt the parameters of friction stir welding and the answers to the optimum conditions found by the grey relational analysis. Rotation Speed is the most influential parameter for determining the high standard of the welded joints that were fall behinded by Force and Feed using Variance Analysis (ANOVA) and validated by confirmatory experiments.
