FIELD: process engineering. ^ SUBSTANCE: invention may be used for welding by mixing of welded parts made, mainly, from aluminium alloys in space engineering, machine building, etc. Case is furnished with bearing collar and stem to be clamped in rotation drive. Head with working rod on its end is arranged in said case. Manifold comprises device to feed coolant via tool case inlets and is communicated with the system of cooling channels made inside said case. Ait intakes of aforesaid device are secured on case outer surface to entrap coolant in rotation of tool head and communicated with tool case inlets. Inlets of air intakes are directed toward tool rotation. System of cooling channels is communicated with cavity made in case, in bearing collar zone, and with outlets made in case top section. ^ EFFECT: higher durability due to efficient cooling, high quality of welded seam. ^ 2 cl, 4 dwg |
