The fsw friction stir welding process was invented by Wayne Thomas of the Cambridge Welding Institute in the United Kingdom in 1991. TWI further developed and patented this process.
FSW friction stir welding refers to the use of the heat generated by the friction between the high-speed rotating welding tool and the workpiece to locally melt the welded material. As the welding tool moves along the welding interface, the plasticized material flows from the front to the back under the action of the frictional force of the rotating welding tool and forms a dense solid-phase welding seam under the extrusion of the welding tool.
FSW friction stir welding is a solid-state joining process. Solid-state welding refers to the process of joining or welding workpieces without including a molten state. This connection technology is energy-efficient and environmentally friendly. It is mainly used for friction stir welding in automotive industry and aerospace industries. FSW friction stir welding is a process that does not consume tools when connecting workpieces. Therefore, it is called a non-consumable tool. Insert the non-consumable rotating tool with a pin and a shoulder into the sheet to be joined or the adjacent edge of the sheet, and move along the joint line until the end. It is considered to be the most important development in metal joining technology, and due to its energy efficiency, environmental friendliness, and other characteristics, it is a "green" technology.
The mechanical properties of the metal will not be reduced after the welding process of fsw friction stir welding. FSW friction stir welding does not produce smoke or unwanted molten metal splatter. The safety level is in line with standards during the fsw friction stir welding process, with no risk of injury. FSW friction stir welding does not require consumables, filler metal, or protective gas during this process. It can be used in any position, such as horizontal and vertical. Friction stir welding is a "green" technology because it does not produce any health-hazardous materials that may lead to environmental or personnel damage. FSW friction stir welding can be applied to various types of joints such as overlap joints, butt joints, T-shaped joints, and corner joints. Fsw friction stir welding does not require cleaning of the metal surface. Contact for friction stir welding services.
FSW friction stir welding is used in shipbuilding companies to weld most components of ships. FSW friction stir welding is mainly used in the aerospace industry to connect or weld larger parts such as wings. FSW friction stir welding is used to fix many parts in the automotive industry. FSW products used in railways. FSW friction stir welding is also used in metal manufacturing work.
