MANUFACTURING METHOD FOR SUPERCONDUCTING COIL AND SUPERCONDUCTING COIL

PROBLEM TO BE SOLVED: To provide a manufacturing method for a superconducting coil which receives no thermal damage in a superconductor wire, inhibits a heating deformation due to a welding, and obtains a high accuracy on an assembly while improving a productive efficiency. SOLUTION: In the manufacturing method for the superconducting coil, the superconductor wire on which an insulating material is wound is housed in a groove worked to the surface of a stainless band plate, a stainless cover body worked in a fitting shape with the opening section of the groove is assembled, and a joint section between the stainless band plate and the stainless cover body is sealed by the welding. In the manufacturing method for the superconducting coil, a welded joint section is welded by laser beams and a plurality of heat sources of arcs. COPYRIGHT: (C)2007,JPO&INPIT
