摘要： [PROBLEMS] To provide a method of welding a metallic glass and a crystalline metal by shifting a high-energy beam scan area from a butting face thereof to the metallic glass side, to fall within a composition range required for glass phase formation of a metallic glass base material in a simplified assured manner. [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.

A metallic glass (1) and a crystalline metal (2) are butted against each other to define a groove space (Y) over a groove formed on the side of the crystalline metal (2).
