Parametric Optimization of Friction Stir Welding for Al 6063 alloy using Taguchi Method

Abstract

FSW, also known as friction stir welding, is a relatively new kind of welding that utilizes solid state technology to join together materials that are analogous to one another but not identical, in particular aluminum alloys. Welding by friction stir (FS) provides a number of benefits over more conventional methods of fusion welding, and it has the potential to be employed successfully in the shipbuilding, aerospace, automotive, and railway industries, among other fields. The present research work is focused on comparative study of friction stir welding processes parameters for joining the sample of aluminium alloy AL 6063 as a parent material or material of work piece. Orthogonal array L9 was used to conduct the experiment based on the requirement of various levels and input parameters to evaluate the performance characteristics such as UTS and hardness. The signal to noise  (S/N) proportion and the examination of difference (ANOVA) were utilized to think about and assess the material attributes at weld zone for parent material. The optimum values were predicted using MINITAB – 18 software, which were validated by conducting the confirmation experiments.
