A welding window device includes an elongated body that defines a welding cavity that extends through the body from a top side to a bottom side. The welding cavity is framed by an inlet end, an outlet end, and lateral sides of the body. The body includes one or more gas channels inwardly extending through one or more of the first lateral side or the second lateral side from an inlet opening in the inlet end toward the outlet end of the body. The gas channels include nozzle openings inwardly oriented toward the welding cavity. The gas channels are positioned in the body to direct a gas into the welding cavity during welding of other bodies together within the welding cavity.

An orbital welding device (1), having a welding current source (10) in a welding current source housing (11) and a base controller (12), and an orbital welding head (20) connected to the welding current source (10) by a cable (2), the orbital welding head (20) having a pipe mount (21) and a welding electrode holder (22) mounted rotatably with respect to the pipe mount (21) for holding a welding electrode (23). A motor (31) is designed to drive the welding electrode holder (22). The orbital welding head (20) has a chamber (50) for shielding gas, and an electrical circuit (60) that is connected: to a position sensor (41) designed to generate a position value (41.1); and/or to a memory device (61) designed to store one or more loading values (61.1) and/or one or more calibrating values (61.2) in the memory device (61).

A glove box has an enclosure having a glass window top and gloves mounted to the front wall. The enclosure can be tilted to so that one or other, or both, of the work piece and the window can be placed at an angle such as may facilitate processing. The glove box has an environmental control system to both to permit flushing with inert or other desired gases, and to permit heating or cooling. The workstand may have cooling passages as well. Controls are mounted inside the enclosure chamber to permit the operator to change working parameters without removing his or her hands from the gloves. A parameter status display may be located outside the enclosure. The window may be provided with a movable smoked glass filter for use during welding. The workstand may be independently adjustable for angle within the enclosure. The glove box has electrical and cooling service penetrations to permit use of a welding electrode.

The embodiments relate to a method for additive manufacturing of a component made from a metal matrix composite for a vehicle. In a step of the method, a plurality of elongated filaments is provided. In another step, metallic powder is provided. In a further step, the metal matrix composite component is additively manufactured by melting the metallic powder.

A weld-on damaged fastener removal device has a weld cup with a deep concave form, and a detachable handle attached to the weld cup. The weld cup has a base and sidewalls that define a hex-shaped outer surface for accommodating a drive tool for rotating the device. A circular hole extends through the base, and a cone-shaped protrusion surrounds the hole. In use, the weld cup is positioned with the hole in the base of the weld cup aligned with the fastener, and the cone-shaped protrusion protruding toward and engaging the exposed end of the fastener. The handle is used to position and hold the weld cup on the fastener while welding the device to the fastener around the perimeter of the hole. A wrench or pry bar can then be used to apply a rotating or pulling force to the weld cup to remove the damaged fastener.
