Abstract

A method for producing a superconducting wire (10), wherein an internal wire (1), which contains superconducting filaments (4), is provided with a normally conducting stabilizing structure (9), is characterized in that, in a continuous or quasi-continuous process, one or more sheath elements (2; 2a, 2b) are shaped and/or placed around the internal wire (9), so that the entire circumference of the internal wire (1) is enclosed by one or more sheath elements (2; 2a, 2b), and all seams (6; 6a, 6b; 16; 16a, 16b) of sheath element ends (5a-5d; 15a-15d) facing each other are soldered and/or welded. A method for producing a superconducting wire is thereby provided, which restricts the cross section of the superconducting wire to a lesser extent and which permits the use of lead-free solder.
