    Abstract: PROBLEM TO BE SOLVED: To firmly join dissimilar metal sheets with each other by using both the adhesion by an adhesive and the spot welding. SOLUTION: A dissimilar metal sheet joining method includes a layering step of superposing an aluminum alloy sheet 1 and a plated steel sheet 2 on each other via an adhesive 5, a preheat step of holding the metal sheets 1, 2 superposed on the layering step between a pair of electrodes 7, 7 for the spot welding and pressing them, and running the current between the pair of electrodes 7, 7, a cooling step of pressing the metal sheets 1, 2 with the pressure higher than that when starting the preheat step while stopping the conduction between the electrodes 7, 7 after the preheating step, and continuing the pressing step for the predetermined cooling time, and a welding step of welding the metal sheets 1, 2 by running the current higher than the conduction current value in the preheating step between the pair of electrodes 7, 7 while pressing the metal sheets 1, 2 with the pressure higher than that when starting the preheating step after the cooling step.

    Abstract: PROBLEM TO BE SOLVED: To provide a disk brake capable of stabilizing welding quality of friction-stir welding. SOLUTION: In the disk brake, a brake pad is pressed against a disk by a piston caused to slide in a bore 38 of a cylinder 45. The cylinder 45 is constituted by a cover member of a bottom portion and a cylinder body 58 having an opening closed by the cover member welded by friction stir welding. A thickness of an inner side of the cylinder body 58 in a disk radial direction is greater than a thickness of an outer side of the cylinder body 58 in the disk radial direction.

    Abstract: PROBLEM TO BE SOLVED: To prevent a member to be welded from being deformed by excessive heat, by reducing thermal influence when a general welding member including a bracket or the like is welded to the member to be welded.
    SOLUTION: In the arc welding apparatus 1, a bracket 2 held on a welding head 6 is welded to a pipe 3 by arc welding. The bracket 2 is provided with a hollow cylindrical body 5, which is formed into a hollow conical shape having a diameter increasing from the bracket 2 to the open end 10. The open end 10 of the cylindrical body 5 of the bracket 2 held on the welding head 6 is lifted from the state in contact with the pipe 3, and fused through arc formation between the tip end of the cylindrical body 5 and the pipe 3, and the open end 10 of the cylindrical body is pressed against the pipe 3; thus, the bracket 2 is welded to the pipe 3.

    Abstract: PROBLEM TO BE SOLVED: To provide a fuel rail for a high-pressure direct injection internal combustion engine having a structure that an injector holder and a fixing bracket are directly fitted to a rail body, capable of securing the positional accuracy of the injector holder even if thermal deformation is caused during temporary installation and brazing when assembling the rail, and having excellent sealing performance and high quality. SOLUTION: Components of the fuel rail for the high-pressure direct injection internal combustion engine are formed of steel or stainless steel, and the components are brazed to one another. The brazed components are finished by cutting and/or burnishing after the brazing. COPYRIGHT: (C)2010,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To provide a joining structure of a metal workpiece and a joining method thereof having less limitation in a joining location.
    SOLUTION: Joining surfaces 1a and 2a rising to the direction to workpieces 1 and 2 as mating members are formed on at least one of a pair of the metal workpieces 1 and 2 joined with each other. An adhesive agent 4 of a chain-reacting type is disposed in a gap 3 between the workpieces 1 and 2 formed by rising in joining. The adhesive agent 4 of the chain-reacting type is successively cured by autogenously generating internal energy by energy imparted from the outside. A portion where the workpieces 1 and 2 face with each other directly (welding portion 5) is welded by a laser beam 31, and the energy for curing is imparted to the adhesive agent 4 by the laser beam 31.
