ABSTRACT:
Superconducting tapes having an inner laminate comprised of a parent-metal layer, a superconductive alloy layer on the parent-metal, a reactive-metal layer, and an outer laminate soldered thereon are joined in a superconducting joint by the method of this invention. The outer laminate is removed to form exposed sections, and the tapes are positioned so that the exposed sections are in contact. A melt zone within the exposed sections where the exposed sections are in contact is melted. The melt zone is at least large enough to provide sufficient parent-metal, superconductive alloy, and reactive-metal to form a melt that resolidifies as a continuous precipitate of the superconductive alloy. The melt resolidifies as a continuous precipitate of the superconductive alloy that is continuous with the superconductive alloy on the superconducting tape. Optionally, sections of the outer laminate material corresponding to the size of the exposed sections are bonded to the outermost surfaces of the joined exposed sections.
