    Friction stir welding (FSW) is a solid-state joining process that uses a non-consumable tool to join two facing workpieces without melting the workpiece material. [1][2] 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 is a solid-state process that was patented in 1991 by The Welding Institute (TWI) of Cambridge, England [5]. This patent is now expired. Since its invention the process has generated significant interests in the R&D community. By 2007, 1800 patents had been issued relating to Friction Stir Welding [6].

    Friction stir welding (FSW) is a relatively new solid-state joining process. This joining technique is energy efficient, environment friendly, and versatile. In particular, it can be used to join high-strength aerospace aluminum alloys and other metallic alloys that are hard to weld by conventional fusion welding.

    Friction stir welding (FSW) is a type of welding that uses frictional heat to join parts together in their solid state–that is, without reaching the materials’ melting point. This CNC technology can produce high-quality welds—fast—that would not be possible with traditional fusion welding.
