View Here : 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. 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 MegaStir offers tooling, equipment, and consulting services for a friction stir welding (FSW) applications to effectively and consistently weld the latest generation of steel-and nickel-base alloys and other high-temperature metals, as well as aluminum alloys.
Friction Stir Welding produces stronger welds—that are easier to make—the External Tank Project Managers chose to use the process on its Super Light Weight Tank, which is made from Al-Li 2195. The Friction Stir Welding process produces a joint stronger than the fusion arc welded joint, obtained in the earlier Light Weight Tank program.
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 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 .

The friction stir welding process is being used and/or evaluated for use within the aerospace, military vehicle, aircraft, automotive, shipbuilding, railway rolling stock industries and most likely others.
As we know that friction stir welding process is a slower welding process, this is because the cylindrical tool turns on the joint to generate heat, and then moving along the length of the joint transmitting that heat.
