Abstract

Underwater Friction Stir Welding (UWFSW) is a valuable adaptation of conventional Friction Stir Welding (FSW) with the potential to supplant fusion welding methods. UWFSW has been widely reported and utilized in several industrial applications. The study compiled information from available sources on the process features, variations, macro-and microstructural characteristics, mechanical properties of the resulting joints, and numerical simulations of the UWFSW process. Furthermore, the study also examined the utilization of UWFSW in the aerospace, aviation and automobile sectors. The current challenges and issues of UWFSW were identified.
