Abstract
The invention relates to a method for the resistance welding of a metal sheet to a further metallic component, wherein the metal sheet is welded to the further component by a flow of electric current for welding in a circuit comprising the metal sheet, the further component, a first welding electrode and a second welding electrode, wherein the first welding electrode is in contact with the metal sheet and the second welding electrode, lying opposite the first welding electrode, is in contact with the further component on the side of the further component that is facing away from the metal sheet, wherein, in a first phase, the metal sheet is subjected at least for a time to a first force at least by the first welding electrode and, in a second phase, the metal sheet is subjected at least for a time to a second force at least by the first welding electrode during the flow of electric current for welding, the second force being lower than the first force.
