摘要
PURPOSE: To provide a welding material which can improve the welding strength without increasing the current value. CONSTITUTION: A nickel oxide powder material is mixed with an aluminum powder or a magnesium powder and made to an aluminum alloy resistance welding powder material. When this powder, material is welded in a state of being inserted between base materials, a hard Al-Ni base intermetallic compound can be crystallized on a welding metal part, and the strength of a welding joining part can be improved.
