Laser cladding is an excellent surface modification technology. By adding cladding material (composite metal powder) on the surface of metal substrate, the laser beam with high energy density and high uniformity is used to make it melt together with the surface of metal substrate to form liquid metal molten pool, which is then naturally cooled and solidified to form a new metallurgical cladding layer on the surface of metal substrate. This new material cladding layer can significantly improve the wear resistance, corrosion resistance, heat resistance, oxidation resistance and electrical properties of the substrate surface, so as to achieve the purpose of surface modification or repair, meet the specific performance requirements of the material surface, and save a lot of material costs.
Direct diode laser cladding has been widely used in the manufacturing and remanufacturing of large mechanical equipment parts in heavy industries around steel, oil, coal, etc., as well as in the repair and strengthening of equipment and parts in shipbuilding, energy industry, light industry, etc. It has become an indispensable and important processing means in industrial production.
Focuslight’s DLight series high-power diode laser cladding system can provide uniform rectangular laser spot with power of 4 – 10 kW and energy density of 15kW / cm², which is suitable for various laser cladding application scenarios of large area and batch processing.
