METHOD OF FRICTION WELDING WITH MIXING Russian patent published in 2019 - IPC B23K20/12 B23K33/00 

FIELD: technological processes.

SUBSTANCE: invention can be used in production of welded structures and semi-finished products, including from aluminum alloys, by friction welding with mixing. One-sided thickening of parts being welded is performed by simultaneous cold deposition. Thickness and width of the thickening of the edges are selected to make the bearing capacity of the welded joint not less than that of the base metal. Width of bulge of each edge is not less than half of diameter of support collar of welding tool, and deepening of support collar into thickened edges of parts is performed by 0.1–0.2 mm.

EFFECT: possibility of welding without preliminary heating to produce a welded joint, which is not inferior in terms of bearing capacity to base metal.
