Abstract

A method for joining high temperature superconducting components while minimizing critical current degradation is provided. The articles formed have critical currents that are at least 80 % of the critical current of the high temperature superconducting components. The invention further provides splicing geometries that facilitate wrapping joined components around a mandrel, tube or the like with minimal critical current degradation and without kinking or flexion of the joined components.
