Friction stir welding is a modern innovation in the welding processes technology, there are several ways in which this technology has to be investigated in order to refine and make it economically responsible. Aluminum alloys have strong mechanical properties when they are welded by using the Friction Stir welding. Therefore, certain parameters of the welding process need to be examined to achieve the required mechanical properties. In this project, a literature survey has been performed about the friction stir welding process and its parameters for 6xxx series aluminum alloys.
