Friction welding is a solid-state process joining two metal objects by applying rotational motion and pressure to the objects. High temperatures generated by friction, transform the point of contact into a plasticized state. The pressure is used to forge a metallic bond between the atoms of the objects. The overall molecular integrity of the original objects remains intact due to the narrow heat affected zone. The technology provides a complete cross-sectional weld without using fluxes or filler metal.
Used by OEM’s across multiple industries worldwide, friction welding holds numerous advantages over conventional welding, the most important being:
