Abstract: Friction stir welding is a solid-state welding technique which is relatively new in the metal joining field and is used for the joining of soft metals like aluminium and magnesium alloys. The present study aims to develop a set of optimum parameters for the defect-free welding of AZ31B magnesium alloy. The effect of tool profile on the quality of the weld has also been studied with the help of two types of tools which are Cylindrical and Truncated Conical tool. Effect of Tool rotational speed and welding speed has also been analysed for its optimality. Charpy Impact test has been used for checking the mechanical properties of the welded specimens. In the study, it is found that the results obtained using the Conical tool were much superior as compared to the results obtained using the Cylindrical tool. It has also been found that the impact strength increases with an increase in the welding speed and decreases with an increase in the rotational speed.
