Abstract

A welding electrode may comprise a welding electrode body and a welding electrode cap that is connected or connectable to the welding electrode body for making contact between the welding electrode and a component for producing a welded connection. The problem of achieving an efficient heating of the sandwich sheet to be welded in a compact layout with the fewest possible modifications of the welding electrodes used heretofore is solved in that an electrically conductive resistance element integrated, or which can be integrated, in the welding electrode and which is connected or connectable in an electrically-conductive manner to the welding electrode body and the welding electrode cap is provided for the heating of the component. Furthermore, a method and a device with the welding electrode and a use are disclosed.
