    Abstract: A combination cutting and welding apparatus for fabricating tailor welded blanks and the like wherein sheets of metal are placed end-to-end in an abutting relationship and welded together along the resulting seam to form a blank for subsequent metal processing. The machine includes two halves which are positioned relative to each other in either a cutting position or a welding position. Each half secures a sheet metal workpiece. At least one of the workpieces is cut so that the workpieces respectively secured by the first and second halves include adjacent edges that mate when the halves are moved from the cutting to the welding position. The workpieces are not unclamped between cutting and welding operations to facilitate the precise mating of the workpiece forward edges. The halves of the apparatus are able to communicate workpieces and finished blanks to each other via crossover conveyor assemblies that allow the workpieces and finished blanks to span a space between the halves. Sensing and positioning assemblies accurately position the workpieces for cutting operations. Offal supports are selectively deployed to support the offal formed by cutting.

    Abstract: A system and method for laser welding. The joint edges of two adjacent sheet metal components are brought into butting relationship on a weld line. A welding head is moved along the weld line while directing a laser welding beam downwardly from its optics to the weld line where it creates a weld joint. In its path downwardly to a focal point at the weld line the beam passes through a stream of air directed transversely of the beam, a shield plate below the stream of air and above the weld line, and a nitrogen filled zone below the shield and above the weld joint.

    Abstract: A process for manufacturing a hollow body made of two mutually welded together metal bars which are flatly disposed on one another. Within an internal high-pressure forming tool in a closed position, the metal bars are widened by introducing a pressure fluid under a high pressure into the parting line existing between the metal bars, until they are placed on the die sinking of the forming tool defining the final contour while forming the hollow body. The metal bar composite is trimmed by a cutting operation, and the pressure fluid inlet area of the metal bar composite is cut off after the widening has taken place. In order to reliably manufacture a flangeless hollow body in a simple manner from two metal bars, the metal bars are seam-welded before entering into the forming tool, and the resulting metal bar composite is then trimmed by a beam welding process in the weld seam. Then for the expanding forming, the metal bar composite is charged into the forming tool such that its trimmed edges are situated within the die sinking of the forming tool, with the metal bar composite being clamped in only in the area of the pressure fluid inlet.

    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: In a method for monitoring and positioning a beam or jet for operating on a workpiece, a first sensor (eg. in the case of a beam, a seam detecting system) ahead of the beam or jet, and/or a preset value, determines the path to be followed by the beam or jet. A second sensor behind the beam or jet monitors the action of the beam or jet. The preset value, or the readings obtained by the first sensor regarding a required position of the beam or jet, is or are compared with readings obtained by the second sensor regarding an actual position of the beam or jet, taking account of the velocity-dependent relative displacement between the beam or jet and the workpiece. The beam or jet is corrected to a basic position if the actual position deviates from the required position.
