The Effect of GTAW Variants on Tensile and Microstructural Properties of AZ31B Magnesium Alloy Joints

In this investigation, an attempt is made to study the tensile and microstructural impact of different gas tungsten arc (GTA) welding processes pulsed current, constant magnetic oscillation welded AZ31B magnesium metal joints. These techniques were chosen because they have potential produce welds with high strength excellent integrity. Five joints produced using each approach, one employing a unique combination parameters. According findings experiment, that manufactured utilising process called yielded superior qualities when compared properties other The improved characteristics these can be ascribed in large part creation smaller grains surface hardness transition region, as well uniformly dispersed precipitates.
