Abstract

The stack for the mixing device consists of individual layers (11a, 11b) assembled from sheet metal strips (13) which leave open flow channels (12). The two adjacent layers touch on bearing points (13b) of the edges (13a) and are there welded together. This is done in one pass with the aid of electrical resistance welding under pressure. The welding electrode arrangement has two electrodes (14, 15) with mating surfaces (14a, 16a), the one electrode (15) being provided with a layer (16) of an electrically insulating material. As soon as the two mating surfaces (14a, 16a) are brought into contact, the interior of the two electrodes forms a cavity corresponding to the shape of the stack to be welded together. Inserted into the one electrode there are mandrel-shaped insulating bodies (17) arranged in a gauge-like manner, which serve for feeding in the layers (11a, 11b) consisting of sheet metal strips (13). <IMAGE>
