CONTACT WELDING APPARATUS Russian patent published in 2005 - IPC

FIELD: machine engineering, namely electrode devices of multi-spot contact welding machines, namely manufacture of wire articles such as gauze.

SUBSTANCE: apparatus includes electric current supply plates placed in single row between electric current supply plates and electrically insulated relative to said plates and one from another. Electric current supply plates are connected with secondary windings of transformer and they have electric contacts with current collecting plates on outer planes. "Dove-tail" guides are provided on lateral surfaces of current collecting plates. Electrode holders having two parts to which electrodes electrically connected with current supply plates are secured are mounted in guides. Pairs of electrodes are connected by means of jumper. It provides possibility for making high quality gauze due to identical electric current in all welded spots.

EFFECT: improved design, enlarged functional possibilities of apparatus due to continuously adjustable cross pitch of gauze in wide range.
