Friction stir welding heads manufacturers tell you that friction welding is a method of using the heat generated by the mutual movement and friction of the workpiece ends to make the ends reach a thermoplastic state, and then quickly upsetting to complete the welding. Friction stir welding heads manufacturers tell you that other welding consumables, such as electrodes, wires, fluxes and shielding gases, are not required during the welding process, and the only consumption is the welding stir head. The friction stir welding stirrer is the key to welding technology. The design of the stirring head directly affects the generation of frictional heat sources and the flow of shaped metal, which determines whether the welding head can be used in a wider range.

The earliest used stirring heads were mainly developed for welding aluminum alloys with a thickness of 1.2-12mm. Friction stir welding heads manufacturers tell you that with the development of friction stir welding technology, a variety of stirring heads have been developed for different welding materials and structures. A retractable stirring head has been developed, which can be used for friction stir welding in different situations.
material selection:
The manufacturer of Friction stir welding heads tells you that the heat source required for friction stir welding mainly comes from the friction heat of the stir welding head and the workpiece, so the stirring head should have good high temperature resistance dynamic and static mechanical properties, as well as other physical properties of wear-resistant materials. .
Friction stir welding heads manufacturers tell you that the commonly used materials for stir welding heads are martensitic stainless steel, medium carbon steel, high carbon steel, tool steel and engineering ceramic zirconia.
