PROCESS AND APPARATUS FOR MULTIPLE-STATION RESISTANCE WELDING ABSTRACT Several electrodes (6) are mounted, electrically insulated, to a joint power transmission plate (5). Each electrode (6) is associated with an isolating switch (30) by means of which the electrode can be galvanically connected to the plate (5). The plate (5) and a second power trans- mission plate (10) carrying the counter electrodes (11) are connected to the terminals of a single source of welding current. The workpieces are clamped between all of the electrodes (6) and counter electrodes (11). Thereupon, preselected groups of the electrodes (6) are supplied in succession with the welding current. By means of the apparatus, very many, closely adjacent sites can be welded in a small space, while the workpieces, secure against deformation, are clamped between all of the electrodes and counter electrodes.
