METHOD OF FRICTION WELDING WITH MIXING AND TOOL TO THIS END Russian patent published in 2017 - IPC B23K20/12 

FIELD: technological processes.

SUBSTANCE: tracking and the moving welding tool regulation feed control according to the loading pressure is carried out during the welding process. The location of the welded edges relative to the backing member, opening of the welded workpieces joint, deformation of the backing member and the geometric position of the welding rod relative to the tool support body are controlled. The loading of the welding rod is changed in an automatic mode to provide a constant gap between its end and the supporting surface of the underlay element by reciprocating the welding rod. The welding tool monitoring and control system includes pressure-sensitive and linear movement pickups connected to the control unit via controllers. Welding rod loading monitoring system ensures that the loading of the welding tool is controlled in automatic mode by the geometrical position of the welding rod with respect to the tool support body, depending on the actual loading of its support part into the material to be welded.

EFFECT: invention excludes the possibility of introducing a welding rod into the bearing surface of the backing member, improves the reliability of the welding tool and the quality of welding.
