ABSTRACT OF THE DISCLOSURE An apparatus and method for connecting the end sections of two superconductors which are to be cooled down to cryogenic operating temperatures wherein each of the superconductors contains at least one superconducting conductor filament embedded in a matrix of normal-conducting stabilizing material is disclosed. The ends of the superconducting conductor filaments are stripped at least partially of the stabilizing material, are directly placed together and welded to each other, and an electrically highly-conducting bridge of normal-conducting material is formed between the stabilizing material of the superconductors. In order to assure an extremely low-resistance connection between the ends of the superconducting conductor filaments, it is provided that these ends be joined together by ultrasonic metal welding. In particular, the ends can be arranged in a special welding form and at least partially welded to the welding form.
