BUTT ELECTRIC RESISTANCE WELDING DEVICE Russian patent published in 2011 - IPC B23K11/02 B23K101/32 

FIELD: process engineering.

SUBSTANCE: invention may be used in butt electric resistance welding of, for example, wire in wire drawing in wire bundle integration units. Stationary foundation and moving foundation pin-jointed therewith are equipped with top electrode and clamping drive, and bottom electrode. Wire upset pneumatic cylinder is coupled with wire end face compression spring. Abrasive wheel to cut faces of welded articles incorporates electric drive mounted to feed said wheel between bottom electrodes in working position and withdraw it into initial position by rotary lever driven by pneumatic cylinder. Built-in centering device is furnished with two pneumatic cylinders and mounted in cantilever on beam fitted on stationary support to move between foundations driven by first pneumatic cylinder of centering device. Dual tabs of centering device serve to receive end faces of parts to be welded together and may be driven by centering device second pneumatic cylinder.

EFFECT: high quality of weld joints.
