Method and device for rotary friction welding of parts to be joined

摘要

For the most symmetrical forming of a welded connection between joining parts (10, 20), a method and a device (100) for rotary friction welding are provided in which a first joining part (10) and a second joining part (20) are rotated relative to one another by a rotating movement (FIG. 7) and while maintaining the rotation (7) are brought into mechanical contact with each other in a common joining zone (6) under propulsion (8) and pressure, by rotation (7), propulsion (8) and pressure in the joining zone (6) Friction heat and plasticized portions of materials of the first and second adherends (10, 20) are generated and while maintaining the propulsion (8) and the pressure, the rotation (7) between the joining parts (10, 20) is braked and stopped and the To cool and solidify plasticized areas. In this case, at least one of the parts to be joined (10, 20) is cooled at least temporarily during the mechanical contact of the parts to be joined (10, 20).
