) is a solid-state welding process which is capable of joining materials which are relatively difficult to be welded by fusion welding process. Further, this process is highly energy-efficient..., various defects associated with the FW process are not present in FSW, leading to outstanding weld strength and ductility. Further, this process is highly energy-efficient and less prone to environment than......
