摘要： A piston main body in a piston assembly of a fluid pressure cylinder includes a first piston member and a second piston member including a plate-shaped member. The first piston member and the second piston member are joined in a state overlapping in the axial direction of a piston rod. The second piston member is not provided with a hole that passes through in the plate thickness direction.

摘要： A method and an apparatus for joining two workpieces by means of a processing beam by forming a weld seam along a lap joint, wherein a gap formed at the lap joint between the two workpieces is filled during welding. The processing beam performs a spatial oscillatory movement parallel and/or perpendicular to the joint during welding. The oscillation parameters of said oscillation, the feed rate, the power of the processing beam and the angle of incidence of the processing beam onto the surfaces of the workpieces are adjusted dynamically during the welding process such that the upper sheet is fused in line with demand and the melt flows from the upper sheet down to the lower sheet thus closing the gap. The gap height is measured permanently during welding and the process parameters are adjusted such that a reliable closing of the gap is made possible.

摘要： Aluminum alloy workpieces and/or magnesium alloy workpieces are joined in a solid state weld by use of a reactive material placed, in a suitable form, at the joining surfaces. Joining surfaces of the workpieces are pressed against the interposed reactive material and heated. The reactive material alloys or reacts with the workpiece surfaces consuming some of the surface material in forming a reaction product comprising a low melting liquid that removes oxide films and other surface impediments to a welded bond across the interface. Further pressure is applied to expel the reaction product and to join the workpiece surfaces in a solid state weld bond.

摘要： An object is to provide a sash coupling structure and a method for sash coupling that ensures omission of the process. The sash coupling structure is made such that on a door frame constituted of a column and an upper sash, a coupling cross-sectional surface of the column and a coupling cross-sectional surface of the upper sash are butted together. The column is constituted of a channel member and an inner member. The channel member and the inner member include adhering portions coupled one another along a longitudinal direction. The inner member is plated. A non-adhering portion, which faces a non-not-yet-adhering portion of the inner member, is formed on the channel member at a butted coupling portion.

摘要： A method of fabricating a precoated steel plate, the method including coating a steel plate by dipping the steel plate in a molten bath to obtain a precoat upon the steel plate, wherein the precoat includes an intermetallic alloy layer and a metal alloy layer. The intermetallic alloy layer is topped by the metal alloy layer. On at least one face of the plate, the metal alloy layer is removed in an area at a periphery of the plate using a laser beam, while leaving at least part of the intermetallic alloy layer in the area. The at least part of the intermetallic layer in the area has a thickness between 3 and 10 micrometers thick.

摘要： A method for producing a welded part from two components, where at least one of the components has a hardened surface. The method can include case hardening the surface of one of the components using a salt bath nitriding process and then welding the case hardened first component to the second component by gas metal arc welding (GMAW).

摘要： A test method is provided to reproducibly test under matched HY100 welds to robustly establish the production parameters for the welding process. The test method comprises forming a ‘U’ shaped groove in a plate to which steel members are welded on the reverse side. The steel members comprise transverse members that extend across the weld. The transverse members are arranged at a density of at least four members for each 0.5 m length of weld and preferably five transverse members. The steel members further comprise longitudinal stiffeners that extend parallel to the weld. The longitudinal stiffeners are arranged at a density of two stiffeners per 0.4 m width of the plate. The high density of stiffeners has provided a reproducible and reliable weld test method that is capable of being used to establish and approve production parameters for the welding process of under matched HY100 welds.

摘要： A valve for use in an internal combustion engine is disclosed. The valve includes a stem friction welded to a head portion. The head portion is cast from a single crystal metal using a casting process that creates little or no grain boundaries. The single crystal metal can be a nickel based superalloys such as CMSX-4, CMSX 3, Rene N5, and Rene N6. By having little or no grain boundaries, defects that occur in other types of casting material, such as large numbers of grain boundaries can be minimized. This allows the head portion and particularly the combustion face to withstand an operating temperature in the combustion chamber in excess of 850° C.
