    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: Friction stir welding tool to facilitate stress reduction within the tool that may include a body, a pin, a tension member, and an end assembly, the tension member and end assembly facilitating axial compression of the pin. The tension member may be decoupled from the pin and/or body of the tool via one or more decoupling members. The end assembly may comprise spring members to provide an axial force to the tension member. The pin may include various features to facilitate stress reduction proximal the pin.

    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.
