NOVELTY - The utility model claims a graphene-containing new YBCO coating conductor welding joint, comprising a welding layer is located at two sides of the YBCO coated conductor and coated conductor, the YBCO coating conductor comprises a copper layer, a silver layer, a Hastelloy alloy layer, a buffer layer, a YBCO superconducting layer, between the YBCO coating conductor with new welding layer comprises graphene. In the utility model, the original Japan Metal Co., Ltd. M705 (Sn-3.0Ag-0.5Cu) solder paste adding graphene powder through mechanical stirring and ultrasonic mixing the graphene powder is uniformly dispersed in the solder paste to form a new solder containing graphene. new welding material by the utility model, the graphene-containing preparation of YBCO coating conductor welding joint, it can effectively reduce the joint resistance, reduces the heating and quench in the service process of the joint, and does not influence the mechanical performance of the joint and broaden the application range of the YBCO CC and further promote the industrial application of YBCO CC.
