Abstract:

Friction stir welding (FSW), which is termed a green manufacturing process, is a very efficient method for joining magnesium alloys. In this research work, dissimilar Mg-Al-Zn magnesium-alloys have been welded at different operating conditions using FSW method with the aim of optimizing the tensile-strength (TS). The maximum value of TS was 234.86 MPa which was obtained at 15 mm of shoulder-diameter ( SDTool), 40 mm/min of welding-speed (WS) and 1000 rpm of tool-rotational-speed (TRS). Further, mathematical model for TS was developed to optimize the TS using desirability approach. The desirability approach predicts the optimized value 248.83 MPa at 15 mm of SDTool, 30 mm/min of WS and 1000 rpm of TRS.
