We applied a new solid state bonding technique to the joints of the forced-cooled superconducting poloidal coils for LHD. The NbTi/Cu wires of the cable-in-conduit (CIC) conductors were joined superconductively by this technique to realize the low electrical resistance and compactness. We make several joint samples and study the joint condition among the NbTi filaments. By scanning electron microscopy (SEM) we make sure that the filaments are joined with very narrow gaps. We measure the magnetization of the joint using a superconducting quantum interference device and estimate the effective diameter of the filaments to be about 90 μm. This value shows that the joint is magnetically stable by the adiabatic theory
