DEVICE AND METHOD FOR (ULTRA-HIGH-SPEED) LASER CLADDING

摘要

The present invention relates to a device for laser cladding, in particular for ultra-high-speed laser cladding (EHLA), comprising: - at least three drive columns (2); - a workpiece support (1) for a product to be manufactured, the support being positioned centrally between the drive columns (2.1, 2.2, 2.3) and/or a support plate (20) for a welding head (22), which - is movably connected to the drive columns (2.1, 2.2, 2.3) in three spatial directions (x, y, z) via multiple tension-compression struts (15) and revolute joints (3, 4) that are fixed on the ends thereof, wherein - each drive column (2.1, 2.2, 2.3) has at least one inner guide rail (5) facing the workpiece support (1) and/or the support plate (20) with an inner carriage (6) running in said rail for moving the workpiece support (1) and/or the support plate (20) in the three spatial directions (x, y, z) and has an outer guide rail (8) with an outer carriage (11) running therein for guiding a counterweight (9) vertically in the opposite direction to the inner carriage (6); - and a welding head (22). The invention further comprises a method for carrying out ultra-high-speed laser cladding (EHLA).
