METHOD FOR MAKING ELECTRODE WITH WEAR RESISTANT INSERT |
摘要 |
welding processes and equipment, possibly manufacture of electrodes for spot contact welding machines and arc plasmotrons for welding and cutting. SUBSTANCE: method comprises steps of forming in blank working portion of electrode and its cooling duct; forming protrusion on end of blank at side of working portion of electrode and making opening in said protrusion for placing in it wear-resistant insert; fixing insert simultaneously with formation of working portion of electrode and pressing out its cooling duct; performing the last two stages by cold die forging process ; making opening for wear resistant insert by pressing it out or by drilling; wrapping with liner cylindrical surface of wear resistant insert before placing it into opening. EFFECT: significantly increased contact surface area between joined members of electrode. 5 cl, 7 dwg
