The multi-seeding and welding techniques are employed to join top seeded melt textured domains of YBa2Cu3O7−δ along the a- or b-direction. Silver doped Y123 is used as a welding compound. In the case of the dual seeded sample, micro-structural features and trapped field maps reveal that cracks existence and large non-superconducting agglomerations at the frontier between the two domains lead to a bad junction quality. On the contrary, the results obtained on the welded sample show that the spacer material has effectively grown from the textured domains and that the junction is clean enough to allow superconducting current to flow from one domain to the other.
