    Abstract: An apparatus for working material employs a tilting mechanism which tilts a head about a theoretical point disposed upon the sheet material. The welding or cutting head is defined as a laser head and the pivot point corresponds with the laser beam focal point. The laser head projects a laser beam directly upon the sheet material without the use of redirecting steerable mirrors. At least a pair of tilting mechanisms are employed to tilt the welding or cutting head along differing rotational planes. Various axial slides are employed in combination with a gantry. A laser vision system tracks a welding seam and a pre-weld gap. The tilting mechanism creates a tailored blank butt weld between dissimilar materials. A method of operating the present invention is also provided.

    Abstract: A system for gauging the relative positions of two opposing joint edges on sheet metal components prior to welding. The system comprises a gauging assembly including two pairs of gauging pins which are movable between a retracted position and a gauging position. Each pair of pins defines a separate edge contact line. When each joint edge has contacted both pins in a respective pair, electrical circuitry indicates as much and the components are clamped in this relationship.

    Abstract: In general, the present invention pertains to an apparatus and control system for working sheet material employs a tilting mechanism which automatically tilts a head about a theoretical point disposed upon the sheet material. In another aspect of the present invention, the head is defined as a laser head and the pivot point corresponds with the laser beam focal point. A further aspect of the present invention provides a seam tracking device and control system which automatically adjust a welding head height relative to the sheet material as a datum rather than relative to a gantry or other structure supporting the welding head. In yet another aspect of the present invention, an optical seam tracking device is employed to automatically tilt the welding head along differing rotational planes. In still another aspect of the present invention, various axial slides are employed in combination with a gantry. A further aspect of the present invention uses a seam tracking device and microprocessor to track a welding seam and move a welding head predetermined amounts due to sensed pre-weld gap widths. Another aspect of the present invention uses an automated tilting mechanism for creating a tailored blank butt weld between dissimilar materials. A method of operating the present invention is also provided.

    Abstract: The present invention relates to a system for welding a joint edge of a first sheet metal component to a joint edge of a second sheet metal component to form a weld joint. The system includes a gauging sub-system which positions each joint edge at a desired distance from a weld line. A sub-system then clamps the sheet metal components in this relationship. A joint edge butting sub-system then moves the clamped components toward each other until the edges are in butting relationship. A laser welding sub-system then moves a welding head along the butted edges to form the weld joint. The laser beam, which forms the weld joint, passes through an air shield in the welding mechanism so that weld splatter from the welding zone is carried off by an air stream and does not reach the welding head optics. The invention also relates to a method of laser welding.

    Abstract: A system for bringing the joint edges of first and second sheet metal components into butting relationship. The components are clamped in opposing clamping assemblies with one of the assemblies being movable toward and away from the other. A fluid motor is mounted on one clamping assembly and a piston extending therefrom is connected to the other clamping assembly through a pair of expandable bladders. By sequentially introducing high and low pressure air to first one bladder and then the other, the movable clamping assembly is caused to move one component toward the other while accommodating any initial misalignment between the edges.
