Taguchi approach and analysis of variance were applied to determine the most influential control parameters for the mechanical properties of the joints of friction stir welded AL 6063 alloy. The evaluation of the effects of process parameters such as tool rotational speed, translational feed and axial force on tensile strength and hardness of friction stir welded AL 6063 alloy were investigated in this study. On the analogy, nine experiments were performed based on L9 orthogonal array of Taguchi’s methodology of three input parameters with three levels. Analysis of variance was employed to find the levels of significance of input parameters. The results indicate that translational feed has the greatest effect on tensile strength and hardness as well. The effects of translational feed is followed by rotational speed and axial force. The results were confirmed by further experiments.
