An extreme low-resistance NbTi superconducting wire jointing technology is a key issue for the construction of the scientific superconducting magnet that required high field stability. In this paper, a novel electromagnetic forming NbTi superconducting joint technology was developed. The preliminary experiment was done, and the fabrication technique was researched by changing the parameters. The joint resistances were tested using the coil current decay method. The contact resistance properties of the superconducting joint were investigated. The induced magnetic field and electromagnetic force, plastic deformation, and the electrical contact characteristics of the NbTi superconducting joint were discussed. The preliminary results show that the electromagnetic formed NbTi superconducting joint has excellent electrical interconnection property and easy operation.
