摘　　要：二代高温超导涂层带材因其具有较高的临界温度、临界电流密度和工程临界磁场,被认为是绕制下一代高场强超导磁体最具潜力的材料之一。带材接头对于磁体研制必不可少,其制作工艺和性能测试方法成为国内外许多研究机构的关注重点。文中综合目前高温超导涂层带材接头相关的研究进展和成果,对包括涂层带材的工业制备现状、带材接头焊接工艺、性能测试方法、仿真建模研究等几个方面进行了概述。As the advantages of its very high critical current density under high magnetic field and relatively high tempera- ture than the low temperature superconductors, meaning the possibility of reducing cooling cost, the 2G high temperature coated superconductor is considered to be one of the best for developing high magnetic field magnet. Joints are crucial components of su- perconducting magnets. In recent years, there has been substantial effort to develop the reliable technology of joining the coated superconductors and the joints performance testing methodology. This paper provided a review of progress made to date on the production and characterization of joints, containing the progress of commercial high temperature coated superconductor, joints making method, devices and means of joints testing and methods of modeling and simulating.
