A friction stir welded structure (10) includes first and second members (12, 14). The first member (12) has a base (16) defining opposed first and second surfaces (18, 20), and spaced first and second walls (24, 26) extending outwardly from the second surface (20) of the base (16) to define a receptacle therebetween. The second member (14) includes an elongate rib (46) extending from a root portion to a first tip portion, the root portion having a uniform root portion thickness and the first tip portion having a first tip portion thickness not greater than the root portion thickness. The first tip portion is sized for insertion into the receptacle and shaped conformally with the receptacle so that the first tip portion engages a closed end of the receptacle. A friction stir weld joint extends through the base (16) and at least portions of the first and second walls (24, 26) of the first member (12) and into the first tip portion of the second member (14), thereby to join the first and second members (12, 14).

This heat exchanger includes a core and a header tank. The entire peripheral edge of an opening of the header tank welded to the core has a bevel inclined from the internal surface of the header tank toward the external surface thereof at a predetermined bevel angle. At least a portion of the peripheral edge of the opening of the header tank has a second inclined portion inclined from the external surface of the header tank toward the internal surface thereof at an angle larger than the predetermined bevel angle.

[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). 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.

A laser welding method of the present disclosure includes a first step and a second step. In the first step, a first end of a first workpiece is positioned such that the first end of the first workpiece is overlapped on a second end of a second workpiece to form a corner joint. In the second step, the first end forming the corner joint is irradiated from above with a laser beam. Additionally, the first end is positioned to protrude relative to the second workpiece in the first step.
