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. Heat is generated by friction between the rotating tool and the workpiece material, which leads to a softened region near the FSW tool.
This webpage is aiming to provide basic information about friction stir welding (FSW) technology, which is a new high-tech way of metallic material jointing used mainly on aircraft and spaceship structures. The technology itself is quite simple and cheap. It hasn't been spread more widely because accessibility of information about FSW is rather low.
Friction Stir Welding is environmentally friendly, with a process that features low energy input and requires no consumables, flux, filler material, or shielding gases to run, like conventional welding methods. Friction Stir Welding also does not emit smoke, fumes, or gases that need to be exhausted on the back end.

Friction Stir Welding, FSW, Wayne Thomas and Solid state welding at TWI, Friction Stir Welding FSW is a solid-state process which produces welds of high quality in difficult-to-weld materials such as aluminium, and is fast becoming the process of choice for manufacturing lightweight transport structures such as boats , trains and aeroplanes .
Friction Stir Welding (FSW) is a solid-state joining process invented by TWI in 1991 capable of producing faster, higher quality welds than traditional fusion welding by using an accurate, repeatable, and environmentally friendly process.
Friction stir welding (FSW) is capable of fabricating either butt or lap joints, in a wide range of materials thickness and lengths. During FSW, heat is generated by rubbing a non-consumable tool on the substrate intended for joining and by the deformation produced by passing a tool through the material being joined.
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.
