The invention relates to a grid welding machine operating on the electrical resistance welding principle and having continuous forward feed of the longitudinal wires. Groups of rotary electrodes and counter-electrodes cooperate in pairs and are arranged above and below the feed path of the longitudinal wires respectively. The electrodes and counter-electrodes are formed as rollers, opposite each electrode roller on the far side of the feed path of the longitudinal wires a counter-electrode being disposed in the same plane. The electrode rollers are spring-loaded individually in the direction towards the associated counterelectrode roller. Between the counter-electrode rollers and coaxially therewith there are arranged substantially circular cross-wire feed discs each having a number of grooves provided at angular intervals along the periphery of said disc for receiving said cross-wires. The feed discs are fixed for rotation on a driving shaft and the counter-electrodes are mounted on and rotatable relative to the driving shaft.
