Resistance welding process for workpieces with a high slenderness ratio

摘要

To completely weld a workpiece having a high slenderness ratio, in particular a housing frame (1) with associated base (2) and lid (3), two welding electrodes (5) are put on opposite one another with a certain applied pressure. According to the invention, the welding current is conducted essentially via a metal layer (4), running parallel to the housing frame (1), between the two joining zones (6). To this end, the metal layer (4) has substantially higher conductivity than the parent material of the housing frame (1). Detrimental heating of the housing frame and, for example, the connector pins (9) is avoided. <IMAGE>
