【Abstract】 Welding of Nb-Ti multifilamentary superconducting wire is one of thekey techniques for making various superconducting magnets. Based on the cons-tructional characteristic of Nb-Ti multifilamentary superconducting wire withcopper matrix, the experiments and measurements of stored energy welding aremade in this paper, the butt welded joints of superconducting wire are madesuccessfully by use of a special butt welding device and welding technique de-veloped at Xi’an Jiaotong University. The properties of these joints come upto the advanced standards. This process shows a lot of distinguished characteristics: more reliablewelding technique, simple in equipment and high quality welded joints. It canbe applied io side welding and will be of great value in practice and popula-rization.更多还原
