The present invention relates to a welding method for a second generation high temperature superconducting wire including a substrate, a buffer layer, a superconductor layer, and a stabilizing material layer, wherein parts of the stabilizing material layers contained in two strands of the second generation high temperature superconducting wire are removed, the superconductor layers of two strands of the second generation high temperature superconducting wire exposed by the removal of the stabilizing material layer abut each other and are heated to the melting point of the superconductor layer to melt-diffuse the abutting superconductor layers and weld two strands of the second generation high temperature superconducting wire together. Subsequently, the welded portion is oxygenation-annealed under an oxygen atmosphere to recover superconducting properties of the second high temperature superconducting wire. The above-described configuration of the present invention enables superconductor ...
