A superconducting article includes a first superconductive segment having a nominal thickness tn1, a second superconductive segment having a nominal thickness tn2, and a joint region comprising a splice connecting the first and second superconductive segments together. The splice overlies portions of both the first and second superconductive segments along the joint region, the joint region having a thickness tjr, wherein tjris not greater than at least one of 1.8 tn1and 1.8 tn2.
