Optimization of Friction Stir Welding Parameters of Aluminium Alloy Using Taguchi Method

Abstract

Friction Stir Welding is the most effective welding technique that welds dissimilar metal with accurate mechanical and metallurgical properties. In this research investigation, Aluminium 6061 and Aluminium 7075 grade is used as a base material. The input parameters such as Spindle speed (rpm), Welding speed (mm/min) and Welding time (sec) are used when the output parameters is Tensile strength in terms of N/mm2. Taguchi L9 orthogonal array is used to identify the ranking process and Analysis of variance is used to identify the most significant parameters and contribution of process parameters. By using experimental results, the optimized parameters are analyzed and confirmed.
