RESISTANCE BUTT WELDING MACHINE Russian patent published in 2019 - IPC B23K11/04 B23K11/25 

FIELD: metallurgy.

SUBSTANCE: invention relates to the field of articles resistance butt welding. Machine includes a housing, movable and stationary clamps mounted thereon, connected to the parts to be welded clamping devices, fixed on the clamps bases, electromechanical drive of flashing and setting, connected to the movable clamp, welding transformer with cooling system, the welding transformer voltage levels switch, relay panel, control panel, limit switches unit and the welding transformer switching on contactor. At that, the machine is equipped with a controller, which input is connected to the installed in the limit switches unit of the heat treatment stage beginning signal supply limit switch, and through the symistor and installed on the relay panel the contact relay the controller output is connected to the welding transformer switching-on contactor.

EFFECT: use of the invention due to the possibility of the product heat treatment performance after welding by the welding device allows to improve the weld seams quality and to obtain the desired weld seam metal microstructure.
