Friction stir welding (FSW) is particularly suitable for joining non-ferrous metals with a low melting temperature. It is also possible to join material combinations such as aluminum and steel with this solid-phase joining process. The Friction Stir Welding technology is ideal for sealing of a battery housing. With the solid phase joining process Friction Stir Welding, mixed compounds such as aluminum with steel or non-ferrous metals with a low melting temperature are optimally and economically

Friction stir welding is a solid-state joining process that uses a non-consumable tool to join two facing workpieces without melting the material. Heat is generated by friction between the rotating tool and the workpiece material which leads to a softened region near the FSW tool Friction Stir Welding (FSW), invented by Wayne Thomas at TWI Ltd in 1991, overcomes many of the problems associated with traditional joining techniques. Friction welding is also used with thermoplastics, which act in a
