Popis: The following paper describes the thermal analysis on friction stir welded aluminum alloy AA 6061. The tool for this investigation is made up of high-speed steel material. We considered tool profile as tapered and the pin is with threaded and without threaded and also discusses the process parameters and their effects of thermal analysis of similar welded aluminum alloys. The joint is fabricated at a tool rotational speed of 825 rpm, feed rate of 32 mm/min and angle of 3 degree for the joining process. There is no surface-level cracks in a welded region by using liquid penetrant testing (NDT) method. The heat transfer model and evolution of temperature during the process of FSW are calculated theoretically, and the values of heat rate and peak temps are evaluated. These are compared with practical analysis values based on ANSYS values.
