Summary

Friction stir welding (FSW) is a patented joining process, which was invented at TWI [1, 2]. A wear resistant rotating tool is used to join sheet and plate materials such as aluminium, copper and lead. In laboratory experiments, magnesium, zinc, titanium and steel have been friction stir welded. It was also possible to join cast magnesium to wrought aluminium by FSW. The welds are made below the melting point in the solid phase. The excellent mechanical properties and low distortion are attributed to the slow heat input and lack or melting. As it is a solid state process, friction stir welding permits joining of materials that cannot be welded with conventional fusion welding processes.
