ABSTRACT:
A process for joining ceramic superconductor fibers with a channel to fabricate a superconductor wire includes concertedly drawing the fibers and the channel together to feed the fibers into the channel. A flowable solder paste is continuously dispensed into the channel over the fibers. The combination of channel, fibers and solder paste is then subjected to a rapid rise in temperature which melts the solder. The molten solder is then frozen to encase the fibers in the solder and attach the solder to the channel to create a superconductor wire.
