Friction stir welding (FSW) is a solid-state joining process that uses a non-consumable tool to join two facing workpieces without melting the material. Heat is generated by friction between the rotating tool and the workpiece material, which leads to a softened region near the "probe". While the tool is traversed along the joint line, it mechanically intermixes the two pieces of metal, and forges the hot and softened metal by the mechanical pressure, which is applied by the tool, much like joining clay, or dough. It is primarily used on wrought or extruded aluminum and particularly for structures which need very high weld strength.
Simulate FSW using Virfac® is a good way to anticipate the shape of the streamline, and the thermo-mechanical behavior of your part, during and after the process.
Who Should Attend?
FSW is found in modern shipbuilding, trains, automotive and aerospace applications like stiffeners for an aeroplane, and fuel tank for launchers.
