Manual laser deposition welding for repairing centering shaft – Sisma SWA 450F

This video shows the case of manual deposition welding with SWA 450F, our laser welding system with fiber source: the welder guides the filler material "by hand" to the area to be welded. A thin wire with a diameter of 0,3 millimeters is used as filler material in this process. The laser beam melts the wire. The molten material forms a strong bond with the substrate, which is also melted, and then solidifies, leaving behind a small raised area. The welder continues in this fashion, spot by spot, line by line, and layer by layer, until the desired shape is achieved. Finally, the part is restored to its original shape by grinding, lathing or milling.
