Summary:In this paper, a detailed investigation has been carried out to find out the impact of the process parameters including Tool rotational speed, welding direction at constant axial force and with a taper cylindrical pin profiled HSS tool during the Friction stir welding (FSW) of AZ31B magnesium alloy lap joints. This paper evaluates & examines in an elaborate manner, the influence of these FSW parameters in the microstructure & mechanical properties of AZ31B magnesium alloy. In short, AZ31B Mg alloys were friction stir welded by varying several different process parameters and the effects of these parameters on the joint quality, microstructure & mechanical properties were discussed comprehensively. This paper also experimentally proves & suggests the optimized process parameter values to be adopted for effective lap joining of AZ31B Magnesium alloys using FSW technique.
