During laser-assisted arc deposition welding, the laser beam stabilizes and guides the electrical arc. Thus, low dilution rates (<5%) and a precise positioning of the deposition material can be achieved.

With this process, protective coatings can be applied to new workpieces, worn down coatings can be re-built, or repair weldings can be carried out.

Since the coating can be precisely positioned and the thermal input is low, the process is especially suited for thin workpieces or for the work on component edges.

The group “Machines and Controls” offers deposition welding for components made of various materials. This includes all alloys typically used for welding wires.
