Due to the extremely reactive nature of magnesium (Mg) alloys, fusion welding is complicated. In the presence of oxygen, magnesium quickly oxidized. As a result, solid-state fusion welding procedures are the ideal approaches for welding Mg alloys. AZ91 Mg alloy sheets were bonded by friction stir welding (FSW) in this study, and the joint quality was tested using microstructural investigations and micro hardness measures. According to the findings, the joint was defect-free, and the size of the huge intermetallic that emerged in the base alloy was reduced. These findings point to Al dissolution in an Mg matrix. Micro hardness tests demonstrate the enhanced hardness in the weld zone caused by the FSW.
