DIFFUSION WELDING UNIT Russian patent published in 2002 - IPC

FIELD: hot-pressure welding equipment for radio, electronic, and instrumentation engineering. SUBSTANCE: welding unit is provided with additional heater mounted in center of half-finished assembly location and additional regulated power supply. Bottom current-conducting plate of piling device mounts inserts and has through hole accommodating thermocouple. Side surface of additional heater is made in the form of reflector that functions to concentrate thermal action in vicinity of half-finished assemblies. Inserts are made of copper and covered with oxidation preventing chromium- nickel coat. Heating temperature is controlled by means of additional power supply in compliance with thermocouple readings. Proposed unit makes it possible to supply heat and welding voltage directly to parts being joined. EFFECT: improved design. 4 cl, 2 dwg
