Abstract:
A joint structure is ideally suited for use in the manufacture of assemblies and subassemblies in aluminum structures. More particularly, the alternative joint structures and methods of forming joint structures facilitate the assembly of a vehicle body-in-white. The friction welded joints of this invention provide assemblies in which lineals and sheet, cast, or extruded components are joined together.
Abstract:
A tool for making simultaneously a plurality of parallel friction stir welds includes at least one shank for holding in a chuck or collet of a friction stir welding machine, a plurality of friction stir welding pins, and friction stir welding shoulders including at least four working surfaces adjacent said ins, the shoulders and pins mounted in axial relationship; dimensions of said friction stir welding pins and shanks corresponding to dimensions and spacings of said friction stir welds.
Abstract:
A method of welding metal components (24, 26) together including moving a laser beam (20) in a first direction (A) along an interface (22) between a pair of metal components such that in the vicinity of the focused beam, metal from each component is vaporized to produce a keyhole (28) in a pool of molten metal (30). The laser beam (20) is oscillated in a direction (B) different from (e.g., transverse to) the first direction (A) such that the keyhole (28) oscillates through the pool of molten metal (30) and molten metal (30) fills into the keyhole (28) as the position of the keyhole (28) changes.
Abstract:
Friction stir welding tool (10) to facilitate stress reduction within the tool that may include a body (20), a pin (30), a tension member (50), and an end assembly (60), the tension member (50) and end assembly (60) facilitating axial compression of the pin (30). The tension member (50) may be decoupled from the pin (30) and/or body (20) of the tool (10) via one or more decoupling members (62). The end assembly (60) may comprise spring members (64) to provide an axial force to the tension member (50). The pin (30) may include various features to facilitate stress reduction proximal the pin (30).
Abstract:
This invention discloses a monolithic aluminum foot (2) for use with a tractor trailer landing gear. The monolithic foot (2) has a pocket (20) that is adapted to receive the landing gear (4) and one or more support members (32) extending radially outward from the walls (14, 16) of the pocket (20). The support members (32) are integrally extruded with the walls (14, 16) of the pocket (20) during the extrusion of the foot (2). The foot (2) and the landing gear (4) have one or more aligned apertures (28) that are adapted to receive one or more locking members, which lock the foot (2) to the landing gear (4). This invention also discloses an extrusion method of fabricating monolithic foot (2) in tractor trailer gear.

Abstract:
A joinable, ballistic resistant product and methods of manufacturing same are disclosed, comprising at least one ballistic resistant layer; and at least one joinable layer bonded to the at least one ballistic resistant layer; wherein the at least one ballistic resistant layer is composed of a material that sufficiently resists ballistic threats at a lower areal density than comparable materials joinable to a damaged entity; and wherein the at least one joinable layer is composed of a material that is capable of sufficient joinder to the damaged entity.
Abstract:
A method of welding continuous or intermittent lap-penetration joints uses a gas metal buried arc (GMBA) welding process. A first component (22) is GMBA welded to an underlying second metal component (24), by forming an arc (28) between a consumable metal electrode (26) and a surface of the first component (22), depositing metal from the electrode (26) to the first component (22) and producing a pool of molten metal (10) which extends through the first component (22) and into the second component (24). The molten pool metal solidifies into a weld (30) that extends into the second component (24) wherein the weld width at the interface between the components is at least equal to the thickness of the thinner of the first component (22) and the second component (24). The arc (28) is at least partially buried within the thickness of the first component and is moved in the direction of the desired joint location to produce a joint.
Abstract:
A method of joining metal components having the steps of depositing adhesive material between the components and welding the components together via solid-state or fusion welding. The welds are spaced apart from the adhesive material and are produced so as to prevent exposure of the adhesive material to the welding. The two types of bonds (adhesive and welding) are produced in the components separated by time and space.
