摘要： An electromagnetic forming method includes: a step of setting pipe periphery members at plural positions along an axial direction of a pipe material; a step of setting a coil unit on a side of one end, in the axial direction, of the pipe material, the coil unit including a conductor wound portion, conductor extension portions, and a resin-made conductor support portion; a step of setting a support member on a side of the other end, in the axial direction, of the pipe material; a coil unit holding step; a coil setting step; and a swaging step. The coil setting step and the swaging step are performed in this order at each of the plural positions of the pipe material while the coil unit is kept held by the support member.

摘要： An outer panel of a different-material panel structure has a hem part in which a peripheral edge part of an inner panel is held via a resin layer on a folded part formed in the peripheral edge part. A rivet has a shaft part passing through the outer panel, and a rivet shaft recess is formed in the tip of the shaft part. An inner protrusion is provided in the inner panel, and the inner protrusion is disposed in the rivet shaft recess. A fused nugget is formed in the location where the rivet shaft recess and the tip of the inner protrusion come into contact, and a first heat-insulating part including at least the resin layer is formed in the gap formed with the resin layer in between the inner protrusion and the outer panel.

摘要： A metal joined body in which a joint is formed from a first metal member and a second metal member. Brazed joint portions provided intermittently with a brazing material and solder joints filling the spaces between the brazed joint portions with a solder having a fusion point lower than the brazing material, are formed at a seam of the joint. The resulting metal joint has excellent sealing properties and little thermal strain.

摘要： Provided are: a metal composite material in which a metal material and an aluminum casting are integrated with one another so as to exhibit high adhesion strength; and a method for producing the same. The metal composite material has a metal material and an aluminum casting which is layered on the metal material. Projecting alloy sections of the metal material which have a higher melting point than does the aluminum casting are formed on the surface of the metal material. The aluminum casting covers the surface of the metal material and is tightly adhered to the projecting alloy sections.

摘要： 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.

摘要： 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.

摘要： A front stay member is inserted into a through-hole in a bumper reinforcement. A first end of a middle stay member is fitted onto a portion of the front stay member that protrudes from the through-hole until the first end of the middle stay member comes into contact with the bumper reinforcement. A rear stay member is inserted into a second end of the middle stay member until the second end of the middle stay member comes into contact with the step on the rear stay member. A magnetic field shaper is disposed so as to face portions of an outer peripheral surface of the middle stay member that respectively overlap the front stay member and the rear stay member, and the middle stay member is clinched onto the front and rear stay members by applying an electromagnetic force to the magnetic field shaper.
