Friction stir welding. 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.
Friction Stir Welding. A green process 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) 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 Link is the Friction Stir Welding Leader - Leading in Technology, Experience, Capacity & Capability.
Friction Stir Welding (FSW), invented by Wayne Thomas at TWI Ltd in 1991, overcomes many of the problems associated with traditional joining techniques. 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 .
Dissimilar friction stir welding. In the beginning, it is mainly used for joining of aluminum base metals due to existence of solidification defects in joining them by fusion welding methods such as porosity along with thick Intermetallic compounds. DFSW is taken into account as an efficient method to join dissimilar materials in the last decade.
