Abstract
A method and product for coupling the ends of a pair of superconducting cored wires are provided, the core of the wires consisting essentially of a substantially unitary structure of a sintered powered superconducting compound material confined within a tubular element of a metal having an electrical conductivity of at least about 20% of that for pure copper taken as unity which metal forms a clad around the core material. The method comprises providing a pair of superconducting cored wires with the cladding material removed from an end of each of the wires to be coupled together to expose a finite length of said core material. A coupling device comprised of a tubular segment of the same metal as the cladding material is used to join the wires together, the tubular segment having disposed therein a green pellet of the superconducting material. The pellet is positioned inwardly from both ends of the tubular segment to allow for entry of the exposed end of the superconducting cored wires. The tubular segment has an internal diameter corresponding substantially to the outside diameter of the cored wires sufficient to provide an interference fit following insertion into the coupling. T…
