Other materials that have been joined with FSW include magnesium, titanium, copper, nickel and steel alloys, while plastics and metal matrix composites (MMC) have also been explored. FSW has been shown to weld aluminium alloy butt joints with a thickness of between 0.3mm and 75mm in a single pass, depending on the alloy grade and capability of the FSW machine. The process is primarily used in industry to join aluminium alloys of all grades, whether cast, rolled or extruded. The shoulder also acts to contain this plasticized material, which is mechanically mixed to create a solid phase weld. ![]() ![]() It then traverses along the joint line, causing the material to heat and soften. The non-consumable tool, with a profiled probe and shoulder, is rotated and plunged into the interface between two work pieces. ![]() Click here to see our latest technical engineering podcasts on YouTube. National Structural Integrity Research Centreįriction stir welding (FSW) is a solid state joining process that uses frictional heat generated by a rotating tool to join materials.Structural Integrity Research Foundation.
