A metal composite and a metal joining method that are capable of suppressing an influence on joining strength of a friction stir welded section due to a tool hole formed when a tool is extracted, in the case in which two metals are joined through friction stir welding. In an overlapping section in an axial direction in which a first shaft and a second shaft overlap in the axial direction, an inscribed section in which the first shaft and the second shaft come in contact with each other and an non-inscribed section in which the first shaft and the second shaft do not come in contact with each other are formed. In the non-inscribed section, a plate thickness of the second shaft is decreased. Then, a starting point of a friction stir welded section is formed in the inscribed section, and an endpoint is formed in the non-inscribed section.

A brake disc to be mounted on an axle hub, including sliding surfaces with which friction members respectively come into a sliding contact and which face in mutually opposite directions, wherein the brake disc includes: a first member having a disc-like shape and including a mount portion through which the brake disc is mounted on an axle hub and a radially outer portion located radially outward of the mount portion, one of the sliding surfaces being formed on the radially outer portion; and a second member having a doughnut plate shape, the other of the sliding surfaces being formed on the second member, and wherein the first member and the second member are bonded through a protruding portion formed on one of the radially outer portion of the first member and the second member and protruding toward the other of the radially outer portion and the second member.

A beam structure includes a lower cover plate, an upper cover plate and two side web plates jointed between the upper cover plate and the lower cover plate; wherein the two side web plates are arranged perpendicularly to the upper cover plate and the lower cover plate, respectively, to form a hollow box-shaped structure; rib plates protruding outwardly with a plurality of plug heads are welded within the box-shaped structure; the plug heads are respectively plugged in the upper cover plate, the two side web plates and the lower cover plate, and each plugging joint is fixed by laser-MAG hybrid welding from outside of the box-shaped structure. The method includes: assembling two side web plates, rib plates and a lower cover plate on an upper cover plate to form a box-shaped structure; and welding each of joints from outside of the box-shaped structure by laser-MAG hybrid welding.

The construction of vehicle body structure articles by welding sheet metal products to load bearing structural metal components. The sheet metal product is bent at the edges forming hemlines to dissipate heat uniformly in all directions from the welding location. The sheet metal product is welded at the bending knees of the hemlines edgewise to the longitudinal edges of the structural components while holding the outer surface of the metal sheet in alignment with the edges of the structural components.

A different material welded joint in which a first member made of a first material and a second member made of a second material having a melting point lower than that of the first material are joined to each other by welded parts, wherein the first member has a plurality of through-holes and a filler material made of the second material is filled in the plurality of through-holes, and wherein an interval between the through-holes is made wider and/or an area of the through-hole is made smaller at a welding end-side than at a welding start-side with respect to progress of welding.

An exhaust system component for an exhaust system of an internal combustion engine of a motor vehicle comprises a substrate which is held in a substantially cylindrical housing. The cylindrical housing has a housing jacket which comprises a metal sheet bent about a cylinder axis. The ends of the metal sheet oriented in the circumferential direction relative to the cylinder axis form a joint connected with a weld seam. The weld seam is spaced apart from an inner surface of the housing jacket and the ends each have a bevel at least in sections.

A turbocharger wheel (4) and shaft (1) assembly exhibits a frustoconical geometry of welding zone contact surfaces extending to the outer circumference of the shaft (1). This frustoconical geometry not only allows continuous centering of the parts (1, 4) during joining, it also eliminates the problem of stress propagation along a plane. The location of the electron beam is shifted so that only the radially outer segment of the frustoconical contact surface is joined by welding, leaving a radially inner unmelted and unfused zone for maintaining firm contact of the oblique surfaces.

A different material welded joint in which a first member made of a first material and a second member made of a second material having a melting point lower than that of the first material are joined to each other by welded parts at a plurality of welding sections, wherein the first member has a plurality of through-holes respectively corresponding to the plurality of welding sections and a filler material made of the second material is filled in the plurality of through-holes, and wherein apexes of welding beads of the welded parts, which are deposited and formed on a surface of the second member facing the through-holes, are formed independently of each other at each of the welding sections.

A system and method for assembling a plurality of components into an assembly is provided. The system includes an assembling robot and an adhesive dispensing robot. The assembling robot is configured to attach a first sub-assembly to a second sub-assembly. The first sub-assembly includes at least one of the plurality of components, and the second sub-assembly includes remaining ones of the plurality of components. The adhesive dispensing robot is configured to apply an adhesive between the first sub-assembly and the second sub-assembly, after the first sub-assembly is attached to the second sub-assembly, to bond the first sub-assembly to the second sub-assembly.

A method of producing a chassis module (1) with a structural component (3) having a through-going aperture (5) into which a ball joint housing (7) is inserted. An outer periphery of the ball joint housing (7) is connected all round to an edge section (9) of the aperture (5) by a first material-cohesive joining (11) without a filler. In order to stabilize the ball joint housing (7) in the aperture (5), the ball joint housing (7) is additionally connected all round to an inner wall section (13) of the aperture (5) at a location spaced away from the edge section (9), by a second material-cohesive joining (15) without a filler. The chassis module (1) is produced by the method, and the chassis module is in the form of a flanged connector (1) or a multi-point link.
