ABSTRACT:
The invention comprises an apparatus which allows precision alignment of sheet-metal plates of various sizes and shapes such that two of those pieces can be conveyed properly past a laser beam welding device and welded together. This is accomplished by affixing each piece to be welded to a pallet which is adapted to be moved along a conveyance system up to and through the welding station. Prior to welding, each piece is carefully aligned and securely affixed to its pallet such that no further motion is possible during the welding process. Also disclosed are methods for loading and discharging the pieces from the pallets, for returning the pallets to the front end of the conveyance system, for combining several systems according to this invention so as to assemble three or more pieces by laser beam welding, and for finishing the assembled units.
