摘要： 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. 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). Then, electron beam welding is performed in a position shifted from the butt interface toward the metallic glass (1) to form a melt zone (4) which has a composition for forming an amorphous metallic glass, and comprises a top fused sub-region (41) and a lower fused sub-region (42), wherein the top fused sub-region has a relatively wide area including the groove space (Y) defined adjacent to an upper end of the butt interface and on the side of the crystalline metal, and the lower fused sub-region extends from the top fused sub-region to reach bottom surfaces of the metallic glass and the crystalline metal, while being narrowingly tapered in a downward direction.
