摘要

1. Apparatus for producing welded grids from metal wires crossing one another, by means of the electrical resistance welding method, wherein the grid wires are conducted between rows of cooperating cooled electrodes and are welded together under pressure at the wire crossing points by means of an electric surge current, characterized in that a catcher tank (14) for a liquid coolant is provided below the welding zone of the electrodes (4, 5) in order to enable welding in a liquid bath, said tank being open at the top and the upper edges of which lying lower than the feeding plane of the longitudinal grid wires (1) to the electrodes (4, 5), in that a second tank (12) is provided in the catcher tank (14), the upper edges of said second tank lying above guides (3) for the longitudinal grid wires (1) and the side walls of said second tank having openings for receiving these guides (3), an outlet slot (13) for the finished grid and optionally an opening for feeding individual transverse wires (2) to the welding zone between the electrodes (4, 5), and in that between the catcher tank (14) and the second tank (12) a connecting pipe (16) with a pump (15) is provided for delivering the coolant from the catcher tank (14) to the second tank (12).
