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 repairing a discrepancy in a casting, weldment or other workpiece comprised of a material characterized by thermoplastic properties includes excising the discrepancy by cutting, milling, or otherwise removing workpiece material surrounding the discrepancy so as to remove the discrepancy and form a cylindrical hole in the workpiece. The method further includes placing a cylindrical plug in the cylindrical hole and moving a friction stir welding tool around the circumference of the plug to weld the plug to the workpiece.

Abstract: A method of joining metal components (2, 8) having the steps of depositing adhesive material (16) between the components and welding the components together via solid-state or fusion welding. The welds (18) are spaced apart from the adhesive material (16) and are produced so as to prevent exposure o f the adhesive material (16) to the welding (18). The two types of bonds (adhesive and welding) are produced in the components separated by time and space.

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: Se describe un metodo de soldadura continua o intermitente de juntas de traslape-penetracion que usa un proceso de soldadura por arco enterrado de metal de gas (GMBA). Un primer componente (22) es soldado por GMBA a un segundo componente (24) de metal subyacente, mediante formacion de un arco (28) entre un electrodo (26) de metal consumible y una superficie el primer componente (22), deposicion de metal del electrodo (26) al primer componente (22) y producir una acumulacion de metal fundido (10) que se extiende a traves del primer componente (22) y producir una acumulacion de metal fundido (10) que se extiende a traves del primer componente (22) y al segundo componente (24). El metal acumulado fundido se solidifica a una soldadura (30) que se extiende al segundo componente (24) en donde el ancho de la soldadura en la internase entre los componentes es por lo menos igual al espesor del mas delgado del primer componente (22) y en el segundo componente (24). El arco es enterrado por lo menos parcialmente dentro del espesor del primer componente y es movido en la direccion de la ubicacion de junta deseada para producir una junta.
