A new way of welding YBa2Cu3O7-δ bulk textured domains

A welding technique has been employed to join two textured bulk domains of YBa2Cu3O7-δ (Y123) by a spacer layer of textured silver-doped Y123. The influence of the composition of the textured domains and that of the spacer layer thickness on the quality of the junction have been studied. Trapped field measurements have shown that, by controlling these two parameters, good welding can be reached between the different parts and confirmed the high potential of this welding method.
