摘要： A joining method includes: an overlapping step of overlapping a front surface of a first metal member with a back surface of a second metal member; and a welding step of welding the first metal member with the second metal member by hybrid welding, using a hybrid welding machine including a leading laser welding unit and a trailing arc welding unit. In the welding step, laser welding, by irradiating with a laser beam, and arc welding are performed from a front surface of the second metal member, along a preset travel route which is set on an overlapped part formed by the first metal member and the second metal member overlapped with each other, to the overlapped part, and the laser beam is oscillated to cross the preset travel route.

摘要： A die set for bending a metal plate workpiece includes a lower die for placing the workpiece, an upper die having a pressing surface which presses the workpiece toward the lower die by movement, a lower movable part provided in the lower die and being slidable in the same direction as the direction of the upper die movement, and a gas spring elastically supporting the lower movable part from below. The pressing surface of the upper die is moved, contacts with the upper surface of the workpiece and presses the workpiece toward the lower die. The lower movable part being elastically supported by the gas spring from below brings an opposing surface into contact with the lower surface of the workpiece and makes the upper die to be close to the lower die while applying force in the upward which is opposite direction of the upper die movement.

摘要： A cooling device includes a body having a flow passage for a heating medium that passes through the body, a first header made of a resin that has an inlet and covers a first end, and a second header made of a resin that has an outlet and covers a second end. The body has a front face, a back face, a first side face, and a second side face. The body and the first header are bonded to a first bonding face, a second bonding face, a third bonding face, and a fourth bonding face. The third bonding face is a curved surface that protrudes toward a +Y side. The fourth bonding face is a curved surface that protrudes toward a −Y side.

摘要： An edge of each of a first metal member and a second metal member is formed to have a U-shaped cross section with a first horizontal plate projecting from a base edge of a vertical plate, and with a second horizontal plate projecting from a top edge of the vertical plate. The second metal member includes a projecting part. The joining method includes: an abutting step of forming an abutted part by abutting a front surface of the first horizontal plate the first metal member against a second side surface of the second metal member; and a joining step of performing friction stir welding of the first metal member and the second metal member by inserting a stirring pin from the projecting part and moving a joining rotating tool along an inner corner at the top edge of the vertical plate of the second metal member while making only the stirring pin in contact with the first metal member and the second metal member.
