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. The results show that it is possible to fully plan for the comprehensive study in order to evaluate the main, combined, and reactive effects of each of the welding speed, the speed of rotation of the tool, the depth of welded and other variables and factors that affect the mechanical properties of aluminum alloys that have been welded by friction 6xxx. It is easy to forecast the impact of process variables on the friction stir welded aluminum alloy 6xxx series mechanical characteristics through using different experimental design methods like Taguchi Method etc. Also, expensive, Line-consuming, and even insufficient for prediction of material characteristics have been traditional approach of experimentation with several variables as well as reactions. The combined impact of the process variable on mechanical characteristics has been investigated with little effort.
