Abstract:
1. A superconducting wire comprising: an internal wire containing superconducting filaments; a normally conducting stabilizing structure, said stabilizing structure enclosing said internal wire around an entire circumference thereof, wherein said stabilizing structure has one or more sheath elements having mutually opposite sheath element ends; and at least one welded or soldered seam disposed between and connecting together each of said mutually opposite sheath element ends, with at least one said seam extending along an entire length of the superconducting wire, wherein, seen in cross section, all seams of said sheath element ends facing each other extend obliquely with respect to a local internal wire surface and obliquely with respect to a local sheath element surface through a length which is greater than a thickness of the sheath element ends perpendicular to a surface of the sheath element ends, said length thereby being selected to reduce or prevent damage to said superconducting filaments due to heat development generated during welding or soldering of said seams.
