Friction Stir Welding (FSW), invented by Wayne Thomas at TWI Ltd in 1991, overcomes many of the problems associated with traditional joining techniques. FSW is a solid-state process which produces welds of high quality in difficult-to-weld materials such as aluminum, and is fast becoming the process of choice for manufacturing lightweight transport structures such as boats, trains and aero planes. FEA analysis will be performed for friction stir welding of aluminum 5083 and aluminum 7475 at different speeds using ANSYS. Coupled field analysis, thermal and structural will be performed. A parametric model with the weld plates and cutting tool will be done in Pro/Engineer. The speeds are 800rpm, 650rpm and 450rpm. The effects of different tool pin profiles on the friction stir welding will also be considered for analysis. Tool pin profiles are circular. A parametric analysis has been carried out in order to examine the temperature distribution along the weld aluminum plates. The two process parameters i.e. Transverse speed and rotational speed are varied and the temperature profile are drawn and compared with experimental work. In additional to this the effect of these parameters on heat loss has also been scrutinized which facilitates in optimizing FSW process.
