[MEANS FOR SOLVING PROBLEMS] In a welding method for weldingly joining a metallic glass and a crystalline metal together by scanning a high-energy beam in a position shifted from a butt interface between the metallic glass and the crystalline metal toward the metallic glass, it is intended to provide a technique for allowing a composition of a melt zone formed around a welding interface to fall within a composition range required for forming a glass phase in the metallic glass to be joined, in a simple and more reliable manner.
