摘要： This invention provides a laser welding method in which a state where the irradiation energy density becomes excessively high by a plurality of times of irradiation with laser is not caused and a defect, such as a hole, does not occur in a workpiece. In order to achieve the object, a laser welding method for welding a plurality of workpieces by irradiating the workpieces in a stacked state with a laser beam is characterized in that, when the laser beam is reciprocatingly emitted along a fixed welding line, the irradiation positions of a start end A and a termination end A″ of the irradiation are shifted away from each other so that the irradiation energy can be dispersed. Moreover, when the laser beam is emitted a plurality of times in the same direction along the fixed welding line, the irradiation positions of the start ends or/and the termination ends of the irradiation are shifted away from each other so that the irradiation energy can be dispersed.

摘要： According to one embodiment, a welding method includes preparing a welding member that includes aluminum. The welding method includes welding a weld area of a surface of the welding member by irradiating a laser on the weld area in a state in which a gas including oxygen is supplied to the weld area. A concentration of the oxygen in the gas is not less than 1.5 vol % and not more than 10 vol %. The weld area includes aluminum oxide after the irradiating of the laser.

摘要： A joining apparatus includes a pressor that cause the first joint target portion and the second joint target portion to butt against each other, a workpiece moving organizer that moves the first workpiece and the second workpiece along an extending direction of the first joint target portion and the second target portion, a separator that temporarily separates the first joint target portion and the second joint target portion from each other by deforming a part of a butting site between the first joint target portion and the second joint target portion; and a laser irradiator that irradiates a site at which the first joint target portion and the second joint target portion separated from each other approach each other again, with laser light on a downstream side of the separator in a moving direction of the first workpiece and the second workpiece.

摘要： A metal member includes a first plate, and a second plate abutting against and welded to the first plate in at least one butt portion. In the butt portion, a length from a first end to a second end of a welding boundary line between the first plate and the second plate is longer than a length of a straight line connecting the first end to the second end of the welding boundary line.

摘要： A method for producing a welded steel blank (1) includes providing two precoated sheets (2), each comprising a steel substrate (3) having a precoating (5) on each of its two main faces (4), each sheet (2) comprising, on each main face (4), at a weld edge (14), a removal zone (18) in which the precoating (5) is removed over a removal fraction; and butt welding the sheets (2) using a filler wire (20) so as to create a weld joint (22) having an aluminum content AlWJ comprised between 0.1 wt. % and 1.2 wt. %. The composition of the wire (20) and the proportion of wire (20) added is such that the weld joint (22) has: (a) a quenching factor FTWJ such that FTWJ−0.96FTBM≥0, (b) a nickel content NiWJ≤14−3.4×AlWJ and a chromium content CrWJ≤5−2×AlWJ, where AlWJ is the aluminum content of the weld joint (22).

摘要： Provided is a method of manufacturing a molded product that can reduce problems on a reinforcing plate during pressing. In one aspect of the present disclosure, the method of manufacturing a molded product includes welding a first metal plate overlaid with a second metal plate to the second metal plate; and pressing the first metal plate and the second metal plate together. In the pressing, a base surface and a wall surface are formed on the first metal plate; the wall surface is disposed to cross the base surface. In the welding, a first welding is performed on a reinforcing portion of the second metal plate that is overlaid on an area of the first metal plate that is formed into the wall surface; and subsequently, a second welding is performed in a direction crossing a direction of the first welding.
