ABSTRACT:
The disclosure relates to the production by means of an electrical resistance welding method, of grids formed from metal wires crossing over another. The grid wires are carried through between rows of cooperating electrodes and, under pressure, are welded together at the cross points of the wires by an electric current. Each cross point of the wires and the surfaces of the associated electrodes of the grid welding machine, which lie in the welding region, are subjected to the action of a liquid coolant to increase the life of the electrodes and reduce distortion of the grid due to the localized heating of the wires.
