To Study the Effect of the Tool Rotational Speed on Mechanical Properties of AZ61 Magnesium Alloy

The paper summaries results of experiments aimed at the effect of the tool rotational speed on mechanical properties of AZ 61 Magnesium alloys. The fusion welding of mg alloys often produces Hot Crack, Porosity which deteriorates its mechanical properties. To overcome from this problem a FSW can be applied for joining of mg alloys. Five Joints were welded using 900–1700 rpm at Constant axial force & travel Speed. Tensile properties of welded joints were evaluated & macro hardness was also analyzed. Tensile test shows that joint with the rotational speed of 1, 500 rpm, welding speed of 41 mm/m, and axial force of 3 KN showed superior tensile properties, compared to their counterparts.
