Research Progress in Superconducting Joint Technology

Abstract:

Superconducting materials have broad application prospects in multiple fields, thus attracting global researchers to invest in them since their inception. Superconductive connection is a crucial part of the application of superconducting tapes and is also a component of forming persistent mode joints. However, superconducting joints currently have shortcomings in critical parameters, preparation difficulty, environmental impact, and other aspects. Therefore, scholars are constantly innovating and optimizing process methods. The structure of superconducting joints and the preparation methods and performance of four common types of superconducting material joints in recent years were introduced. The shortcomings and defects were summarized, and the future development of superconducting joints was analyzed, providing reference for the development of superconducting joints.
