Method for producing a material-bonded connection between joining partners

Abstract

Method for producing a material-bonded connection between joining partners (10, 14), in particular bipolar plates (12, 16) which are made of or contain metallic material, comprising at least the following process steps: a) Arrange the joining partners (10, 14) parallel to each other such that a joining plane (18) is formed, b) Applying a first electrode (28) to the first joining partner (10) and a second electrode (30) to the second joining partner (14), c) Positioning the first electrode (28) and the second electrode (30) in a lateral direction (38) relative to each other such that an offset (36) of the electrodes (28, 30) is established relative to each other, d) Applying contact forces (40, 42) to the electrodes (28, 30) to create a region (48) with increased compressive stress in the joining plane (18) and e) Generating a narrowed, limited current path (50, 54) between the electrodes (28, 30) in the diagonal direction (52) through the joining plane (18).
