Abstract
Superconductively jointed silver-sheathed Bi-2212 tapes have been newly fabricated. Two types of methods, which are a side joint and a center joint, were employed for the fabrication of superconducting joint. Side joint and the center joint refer to the techniques by which two separate tapes were connected to each other at both terminal sides and the center of an additional intermediate tape, respectively. The center jointing technique is more promising than the side jointing one. However, reduction of the distance between the two tapes is required to realize a high critical current through the jointed part even in the case of the center joint. The resulting jointed tapes proved that the critical current through the jointed part is higher than in the jointless part.
