Effect of Friction Stir Welding Process Parameters on the Mechanical Properties of AA 6061 Aluminum Alloy Using Taguchi Orthogonal Technique

Abstract:

In this investigation, the effect of friction stir welding (FSW) parameters such as D/d ratio, tool tilt angle and welding speed on the mechanical properties of tensile strength, and impact energy of AA 6061 alloy was studied. The experiments were carried out as per Taguchi parametric design concepts and an L9 orthogonal array was used to study the influence of various combinations of process parameters. Statistical optimization technique, ANOVA was used to determine the optimum levels and to find the significance of each process parameter. The results indicate that D/d ratio, welding speed are the most significant factors, followed by tool tilt angle in deciding the mechanical properties of friction stir welding aluminum alloy.
