A stamped part includes a first blank, a second blank, and a weld joining the first blank to the second blank. The weld includes opposing ends. At least one of the opposing ends of the weld is recessed from adjacent edges of the first and second blanks.

A turbine and a turbine-generator device for use in electricity generation. The turbine has a universal design and so may be relatively easily modified for use in connection with generators having a rated power output in the range of 50 KW to 5 MW. Such modifications are achieved, in part, through use of a modular turbine cartridge built up of discrete rotor and stator plates sized for the desired application with turbine brush seals chosen to accommodate radial rotor movements from the supported generator. The cartridge may be installed and removed from the turbine relatively easily for maintenance or rebuilding. The rotor housing is designed to be relatively easily machined to dimensions that meet desired operating parameters.

A first abutting surface, a first welding surface, a first facing surface are formed in a differential case. A second abutting surface, a second welding surface, and a second facing surface are formed in a differential ring gear. In an installing step, the first abutting surface and the second abutting surface are inserted, positions of the differential case and the differential ring gear are determined in an axial direction, a separation portion that spaces the first welding surface and the second welding surface away from each other and that has a non-linear portion is formed, and a void is formed between the first facing surface and the second facing surface. In a welding step, a laser is irradiated to the separation portion and the first welding surface and the second welding surface are welded.

A metal member manufacturing method according to one form of this disclosure is a method of manufacturing a metal member that is thinner at some portions than at other portions. The method includes a formation step of pressing one surface of surfaces of a metal workpiece that are perpendicular to a thickness direction with a press-working die so as to form a raised portion in the other surface, and a cutting step of moving a cutting blade along the other surface to cut off the raised portion by shaving. In the formation step, the raised portion is formed such that the area of a cross-section of the raised portion that is parallel to a moving direction of the cutting blade and perpendicular to the other surface decreases toward an end of the raised portion on a rear side in the moving direction of the cutting blade.

A method for manufacturing an architectural panel and an architectural panel made by the method. The architectural panel may be formed from metal, and the method may start with the processing of a flat metal sheet. The method may include punching holes in a particular pattern into the flat metal sheet, bending the flat metal sheet into a particular shape to form a panel that can be hung from an overhead grid or the like, and printing a desired printing pattern onto the panel. The method may also include a step of coating the panel with a powder coating or a liquid-applied paint finish prior to the printing step. The coating step may occur after the punching step and before the printing step.

Valve bodies and methods of manufacturing the same are disclosed. An example method of manufacturing a valve body includes forming a first duct extending from a first side of the valve body, forming a first wall in the valve body at least partially protruding from a surface of the first duct, the first wall defining a chamber, forming one or more openings in the first wall to fluidly couple the chamber to the first duct, and forming a second duct extending from a second side of the valve body opposite the first, the second duct fluidly coupled to the chamber.

A hinge area and processes of forming the hinge area are described. The hinge area is part of cover of a laptop computer. A material used for the cover is of a certain thickness. Stamping and forming a shape that defines the hinge area is performed on the material. The top of the shape is cut to provide for sides of the hinge area. Squeeze forging operations are performed to thicken the sides, and CNC machining is further performed on the sides.

Pipe connectors and methods of making and using pipe connectors to connect oil or gas pipe in oil and gas production, refining and distribution.
