Abstract: Portable friction stir welding apparatus having a crawler which supports a motor for rotating a Friction Stir Welding tool and is coupled to a drive mechanism for urging the crawler along a predefined weld path on work pieces. The crawler can comprise one member or a set of two or three physically separated members each rotatably coupled to the friction stir welding tool. The friction stir welding tool for making the weld is rotatably coupled to each member and restricts axial displacement of the physically separate members relative to each other. The members are adapted to engage rails on the work pieces which provide at least one of guiding, alignment, fixturing, torque compensation for the members as the friction stir welding tool is rotated and the crawler is moved along a joint.

Abstract: The present invention provides a thin vehicle closure panel design that substantially reduces a thickness (panel gauge plus the perpendicular distance or depth between the panels) of a vehicle hood (5) and the impact effect on the head of a pedestrian struck by a motor vehicle. In one embodiment, the vehicle hood (5) includes a hood shell (15) including an outer panel (25) and an inner panel (20); a unitary foam core (100) positioned between and bonded to the outer (25) and/or the inner panel (20) of the hood shell (15); and at least one recess (10) that corresponds to an underhood component (42). In another aspect of the invention, a vehicle hood (5) is provided in which a latch attachment member (60) and/or hinge members (70) are attached to inner surface (50) of the inner panel (20) of the hood shell (15).

Abstract: Portable friction stir welding apparatus having a crawler (200) which supports a motor (308) for rotating a Friction Stir Welding tool (213) and is coupled to a drive mechanism for urging the crawler along a predefined weld path on work pieces. The crawler can comprise one member (201) or a set of two or three physically separated members (201, 202, 203) each rotatably coupled to the friction stir welding tool. When one member is used to make a weld, it is located on top of the work pieces. When two members are used to make a weld, one member is located on the top of the work pieces and the second member is located on bottom of the work pieces. When three members are used to make two welds simultaneously on an upper work piece and a lower work piece, one member of the crawler is located on the top surface of the upper work piece, a second member is located between the two work pieces, and a third member is located on the bottom surface of the lower work piece. The friction stir welding tool for making the weld is rotatably coupled to each member and restricts axial displacement of the physically separate members relative to each other. The members are adapted to engage rails on the work pieces which provide at least one of guiding, alignment, fixturing, torque compensation for the members as the friction stir welding tool is rotated and the crawler is moved along a joint.
