Abstract: The present invention relates to a method for joining a plated steel sheet, in which at least one of a first steel sheet and a second steel sheet is a plated steel sheet, and the first and second steel sheets overlapped with each other are subjected to an arc spot welding. The method includes press-working the first steel sheet into a desired shape and at the same time forming a linear groove on an overlapping surface with the second steel sheet of the first steel sheet, overlapping the first and second steel sheets, and setting a welding torch with the groove as a target position, and performing the arc spot welding so as to overlap the groove when viewed from a direction perpendicular to the overlapping surface.

Abstract: A method for manufacturing an additively-manufactured object in which deposition is performed by melting and solidifying a metal depending on three-dimensional shape data of a target shape, includes: acquiring the three-dimensional shape data; creating a deposition plan in which a formation track and a heating condition of the metal are determined; determining a difference between a shape of the additively-manufactured object that thermally contracts by cooling after deposition and a shape of the three-dimensional shape data by an operation; modifying the deposition plan until the difference falls within a predetermined allowable range; and additively manufacturing the additively-manufactured object based on the deposition plan in which the difference falls within the allowable range.

Abstract: A screw extruder for extruding a kneaded material, includes: a pair of screws; a casing that houses the pair of screws and includes a supply port; and a roller-die. Each of the screws includes a shaft portion, and a spiral flight portion. The flight portion is formed into a shape in which a radial distance between the surface of the shaft portion and a tip of the flight portion decreases gradually toward a downstream end in an extrusion direction of a kneaded material. The casing has a tapered shape. Within a range between a downstream end of the supply port and a downstream end of the flight portion, a clearance between a top portion of the flight portion and an inner wall surface of the casing at the downstream end of the supply port is larger than a clearance at any other part.

Abstract: Provided are a coil unit for electromagnetic forming capable of stably processing a plurality of portions in the longitudinal direction of a tubular member while preventing the contact between the tubular member and a conductor or the contact between the conductors even when the tubular member is long, and a method for producing a formed article using the coil unit. The coil unit for electromagnetic forming includes: a shaft core member made of a resin; a conductor having a wound portion, which is wound around the shaft core member, and a pair of conductor extension portions; an insulating support; and a resin coating layer formed on the outer peripheral surface of the wound portion. In the insulating support, a conductor holding portion for holding the conductor extension portions apart from each other is formed along the longitudinal direction.

Abstract: A resistance-spot-welded aluminum joint having a type of a nugget that can reduce variations in cross tension strength. The resistance-spot-welded aluminum joint is obtained by layering a plurality of aluminum members and welding the aluminum members together by resistance spot welding. In a cross section of an interface between the aluminum members, a weld nugget formed as a result of the resistance spot welding has a plurality of blowholes aggregated in a central area of the weld nugget within the interface. In a cross section taken in a layered direction of the aluminum members extending through the center of the weld nugget, a blowhole with a maximum size of the plurality of blowholes is formed at a position where the blowhole extends through a center line of the weld nugget extending in the layered direction.

Abstract: A one-side submerged arc welding method, includes joining two steel plates butted against each other by submerged arc welding from one side using a plurality of electrodes. During the submerged arc welding, at least one of electrode distances between adjacent electrodes in an end part region of the steel plates is reduced to be smaller than the at least one of electrode distances in a region in front of the end part region. Variation in heat input into the electrode moved so as to reduce the at least one of electrode distances in a transitional region in which the at least one of electrode distances is reduced is within 20% relative to the heat input at a starting point of the transitional region.
