FIELD: process engineering. ^ SUBSTANCE: invention may be used in producing joints of diverse materials, for example, steel-aluminium, in ship building, aircraft engineering, etc. Holes are bored in part made from higher refractoriness material. Cylindrical tool is used to act on part from lower refractoriness material to allows friction welding with filling said holes by the latter material. Sublayer is applied between parts to be jointed together. Said sublayer is made from material with part melting point below that of part from low-melting material, for example, zinc. In jointing, said sublayer allows soldering joints of parts. For friction welding with mixing appropriate tool may be used. ^ EFFECT: higher strength and tightness of joints. ^ 6 cl, 4 dwg, 1 tbl, 1 ex |
