 The Frictionster Welding, FSW, process has been widely adopted in the aerospace industry due to its ability to produce strong, reliable welds without the need for filler material. Various modifications have been made to the original FSW process to accommodate different geometries and materials, resulting in the development of Refill Frictionster Spot Welding, RFSSW, Stationery Shoulder Frictionster Welding, SSFSW, and Bob and Tool Frictionster Welding, BTFSW. Additionally, new designs and adaptations of existing machinery have been developed to facilitate the FSW process. Furthermore, new materials such as third-generation aluminum lithium alloys have been found to be successfully weldable using the FSW process, resulting in improved weld quality and geometric accuracy.
