    Abstract: A system for clamping a sheet metal component in preparation for welding or the like. A clamping assembly includes a horizontally elongated lower clamping platen and a horizontally elongated upper clamping platen positioned over said lower platen. The upper platen includes an elongated carrier and a series of clamping pads, separately mounted on the carrier for movement toward and away from the carrier. A pair of coil springs between each pad and the carrier bias the pad away from the carrier. The pads are mounted for progressively further movement away from the carrier as they are displaced further from the centerline of the carrier.

    Abstract: The invention provides a tool and method for repairing a sheet metal according which a dented portion of a sheet metal can be easily and appropriately pulled out with a minimal force. The tool has a simple structure and adapted to be used in the method. The tool includes an end of an operation shaft 1 having a given length serves as a handle portion 2, and an arc electrode 3 is affixed to the other end. A support stand 4 is attached to an end of the operational shaft 1. The support stand 4 may include a base 5 through which the operational shaft 1 is inserted and affixed thereto, a leg portion 6 extended from the base 5, and a seat portion 7 attached to the lower end of the leg portion 6. With the configuration as above, the arc electrode 3 is welded to a dented portion r of a sheet metal while the seat portion 7 is in contact with the sheet metal surface R, and the operation shaft 1 is tilted in that state, while the seat portion 7 is pressed against the sheet metal surface R. Thus, the dented portion r joined to the arc electrode 3 is pulled out by leverage.

    Abstract: A method and apparatus for in-situ laser welding of a hemmed joint are applicable for, among other things, production of vehicle doors having inner and outer panels to be joined. In a preferred method, the laser welding of a hemmed joint is carried out while a stable condition is maintained between the inner and outer panels. Locating members of a hemming machine are engaged with the metal sheets to be joined and a compressive force is applied to the panels. A plurality of welding units may be sequentially or simultaneously controlled by a computer. The apparatus includes a first portion for vertically locating the hemmed joint and a second portion for horizontally locating the hemmed joint.

    Abstract: Device for guiding and feeding at least two sheet blanks previously brought edge to edge to form a joint plane, of the type including two units for supporting and feeding the sheet blanks in the direction of a high energy density beam disposed on each side of the joint plane and movable in synchronism with each other. Each supporting and feeding unit includes at least one lower series of carriages or at least one upper series of carriages, these carriages being articulated together in a vertical plane and movable in a direction parallel to the joint plane on a runway constituting a reference plane. Each carriage carries at least one shoe movable relative to the respective carriage in a direction perpendicular to the joint plane. The shoes of at least one of the two series of carriages cooperate with a device exerting a lateral pressure on the edges to be welded of the sheet blanks by a displacement of the shoes in a direction perpendicular to the joint plane.
