摘要： A metal joined body has an iron base body and an aluminum base body that are joined together via a joint layer. The joint layer has a first layer composed of a first intermetallic compound formed on the iron base body side and a second layer composed of a second intermetallic compound formed on the aluminum base body side. The first layer has one or more first protrusions that merge integrally into the iron base body and extend in a pile shape into the first intermetallic compound. The second layer may have one or more second protrusions that are composed of a second intermetallic compound and extend in a columnar shape into the aluminum base body. The first intermetallic compound may contain Al5Fe2, and the second intermetallic compound may contain Al3Fe. The total thickness of the first layer and the second layer is, for example, 2 to 15 μm.

摘要： A vehicle structural component is provided having a substrate with one or more patches applied thereto. The thickness of the structural component is thicker and has added stiffness at the locations of the patches. The patches are bonded to the substrate via full surface bonding. The full surface bonding may be achieved via brazing, resistance seam welding, or adhesive bonding. A bonding layer may be disposed between the patches and the substrate. The patches and the substrate may be bonded via resistance seam welding, where a current and pressure are applied by weld wheels. The patches may be applied to the substrate in the form of a blank, or may be applied after the substrate has been formed and shaped into the vehicle component. The fully bonded patches provide comparable stiffness as a solid material having the same thickness.

摘要： Provided is a resistance spot welding method. The resistance spot welding method for joining a sheet set including a plurality of lapped steel sheets includes: holding the sheet set between a pair of electrodes; and energizing the sheet set under application of electrode force to thereby join the steel sheets together. At least one of the plurality of lapped steel sheets is a surface-treated steel sheet including a metal coating layer on a surface thereof. The energizing includes: a primary energizing step of performing energization to form a nugget portion; a non-energizing step in which, after the primary energizing step, the energization is suspended for an energization suspension time Tc (cycles); and a secondary energizing step of, after the non-energizing step, performing energization for reheating while the nugget portion is prevented from growing. During the energizing, the relations of a particular formula are satisfied.

摘要： A method of resistance spot welding that enables an improvement of a weld strength of steel plates having different plate thicknesses while inhibiting generation of spatters is provided. One aspect of the present disclosure is the method of resistance spot welding, the method including welding a workpiece made of layered steel plates with a resistance spot welding apparatus. The resistance spot welding apparatus includes a first electrode configured to contact a first steel plate among the steel plates, and a second electrode configured to contact, among the steel plates, a second steel plate that is thinner than the first steel plate, and the second electrode being arranged such that the workpiece is interposed between the first electrode and the second electrode. The welding includes welding while moving the second electrode relative to the first electrode in a direction parallel with a plate surface of the second steel plate.

摘要： A method for the manufacture of a cold-rolled steel sheet of thickness ef between 0.5 mm and 3 mm is provided. At least two hot-rolled sheets of thickness ei are supplied and butt welded, so as to create a welded joint (S1) with a direction perpendicular to the direction of hot rolling. The at least two hot-rolled sheets are pickled by continuous passage through a bath, then the assembly is cold rolled, in a step (L1), to an intermediate thickness eint, the direction of cold rolling (DL1) coinciding with the direction of hot rolling. The cold rolling is carried out with a reduction ratio ɛ 1 = Ln ⁡ ( e i e int ) such that: 0 . 3 ⁢ 5 ≤ Ln ⁢ ⁢ ( ei e ⁢ ⁢ int ) Ln ⁢ ⁢ ( e ⁢ i e ⁢ f ) ≤ 0 . 6 ⁢ 5 , then the welded joint (S1) is removed so as to obtain at least two intermediate cold-rolled sheets. Then the two intermediate cold-rolled sheets are butt welded, so as to create a welded joint (S2), the direction of which is perpendicular to the direction of hot rolling, then the assembly of the at least two intermediate cold-rolled and welded sheets is cold-rolled, in a step (L2), to the final thickness ef, the direction (DL2) of the cold rolling step (L2) coinciding with the direction of rolling (DL1).
