Abstract: This article predicts the effect of the input process parameters on the mechanical properties of the weld joint of the aluminium alloy in the friction stir welding process using statistical techniques that are ANOVA, regression and surface response methodology. Mechanical properties of the weld joint almost constant with welding speed at particular tool rotation speed and tool pin geometry. The effect of the tool rotation speed is nonlinear on the mechanical properties. At the moderate tool rotation speed (900 rpm to 1,120 rpm), tensile and percentage elongation are maximum, whereas grains size and hardness are minimum with all tool pin profiles and welding speed. Steeped tool pin profile produces maximum tensile and percentage elongation whereas minimum hardness and grain size value among the all tool pin profile produced surface responses. Stepped tool pin profile produces superior mechanical properties of the weld joint with respect to other tool pin profiles.
