<p>The invention relates to a method for producing a joint between at least one sheet-metal component (1) of steel, in particular of a press-hardened high-strength steel, and at least one sheet-metal component (3) of an aluminium material. In this method, first a solder deposit (2) is fixed on one of the sheet-metal components (1, 3) by an arc or laser process in such a way as to remain secure during transport. Subsequently, by applying an electric current I and applying a compressive force F, pressing the sheet-metal components (1, 3) together, or by inductive heating, the solder deposit (2) arranged between the sheet-metal components (1, 3) and the sheet-metal components (1, 3) are heated in the region of a joining location in such a way that a soldered connection forms between the sheet-metal component (1) of steel and the solder deposit (2) and a welded or soldered connection forms between the sheet-metal component (3) of aluminium material and the solder deposit (2).</p> |
