Abstract: A connection element for an electrical conductor contains a first section to be connected to another component, and a second section having a front surface to be welded to an electrical conductor. The front surface has a three-dimensional form raised in a central region in relation to an edge region surrounding the central region. The connection element is hollow in the region of the front surface.

Abstract: Process for connecting a first electrically conductive component in the form of a flexible electrical line having metal wires to a second electrically conductive metal component, e.g., a second electrical line or a connecting element. The free end of the flexible electrical line is inserted into a sleeve and is pressed with the latter; in addition, the end of the second electrically conductive component that is assigned to the flexible electrical line is inserted into the free end of the sleeve and is brought into contact on the flexible electrical line, and electrical current is run through these two components, by which their ends that lie on one another are melted together, whereby the sleeve is made from such a metal, which has a higher melting point compared to the metal or the metals of the two components that are to be connected to one another.
