ABSTRACT:
Two Nb.sub.3 Sn superconducting tapes are overlapped by an amount equal to about two times the width of the superconducting tapes. A filler material of material substantially similar to the tapes is placed between the two tapes in the overlapped region. A NdYAG laser (4) sends a 20-40 watt beam focused by a lens that heats the tapes to create a bridge of superconductivity material formed over the region where the tapes are joined.
