Satish P Pawar, M.T.Shete

Abstract: Friction stir welding (FSW) is relatively new solid state joining process. This joining technique is energy efficient, environment friendly and versatile. Welding is a multiinput-output process in which quality of welded joint is depends upon a input parameter. Therefore optimization of input process parameter is required to achieve good quality of welding. There are so many methods of optimization in which Taguchi method and Response surface methodology are selected for optimization of process parameter. In this review the effect of process parameter on welded joint studied and optimizes the parameter by using Taguchi method and Response surface methodology. The study of Friction stir welding of Aluminium alloy and High density polyethylene sheets shows the improvement in welded joint quality by optimization of process parameter. The main process parameters which affect the strength of welded joint is tool rotational speed, welding speed, axial force and tool pin profile.
