<p>A work processing table for joining or welding of sheet material, especially for laser fusion welding of metal blanks into a tailored blank assembly, such as e.g. automotive parts or body panels, comprises a vacuum platen/table plate structure (1, 2) with at least two separate surface suction areas (6, 10) for holding a set of adjoining blanks. Said suction areas extend continuously along the opposite walls of a bond processing or a welding trench (5) and are spaced therefrom by blank edge supporting rim areas (8, 9). Advantageously, the welding table contains retractable positioning means (12, 22) mounted integral with the table structure. Said means allow quick and accurate positioning of the blanks relative to the bonding or welding track without interfering with the operative bonding means such as a welding beam and its access area, nor with the blank loading operation.</p> |
