Abstract
An electrical resistance grid welding machine for welding a family of wires as it passes through the machine along a feedpath into a strip of welded mesh which has a row of electrodes and a row of counterelectrodes arranged above and below the family of wires. The electrodes and counterelectrodes are supported at intervals by separate electrode beams which are driven back and forth, thus coupling the electrodes and counterelectrodes in a common motion. Pressure beams, which are connected to the electrode beams by rigid connectors, can be driven only perpendicular to the feed path. These pressure beams transmit the welding pressure to the electrodes but permit the electrode beams to carry out their reciprocating motion. The electrodes are guided in their associated electrode beam so as to be able to shift in the beam and are loaded by springs.
