ABSTRACT:
A method of producing compound-type superconducting wires which are dense and free of voids. The method comprises the step of holding a compound-type superconducting wire having voids in an atmosphere of sufficiently high temperature high pressure gas to collapse the voids and weld the collapsed areas, thereby forming a dense, void-free superconducting wire.
