Long-Focus Water-Cooled Coaxial Annular Powder-Feeding Laser Cladding Nozzle
Presentation of the equipment's characteristics
The Long-Focus Water-Cooled Coaxial Annular Powder-Feeding Laser Cladding Nozzle from Greenstone is designed specifically for high-speed laser cladding / DED (Directed Energy Deposition) where long working distance, high power endurance, and coating consistency are essential. Built for demanding production and repair environments, this nozzle delivers a stable coaxial annular (ring-shaped) powder stream that converges precisely at the deposition zone—supporting smooth melt pool behavior and highly repeatable layer formation.
Engineered to handle high-power laser operation for extended periods, the nozzle uses high thermal conductivity copper (purple copper) to improve heat dissipation, while the water-cooling configuration enhances thermal stability during continuous cladding. The optimized powder delivery structure produces a fine, well-controlled powder stream, helping form dense coatings with reliable bonding and surface quality—ideal for wear-resistant and corrosion-resistant overlays, remanufacturing, and high-value component repair.
With a long-focus design and 19–23 mm working distance, the nozzle is well-suited to complex geometries and applications where standoff distance is critical. Its direction-independent coaxial powder flow supports consistent results on varying contours, reducing typical defects and improving overall process robustness for industrial laser cladding systems.
Stable coaxial powder-feeding process: Helps prevent defects such as porosity, waviness, and direction-related inconsistency.
Excellent powder stream focusing: Enables precise matching between powder focus and laser spot, maximizing powder utilization efficiency.
Adaptive deposition thickness control: Reduces uneven cladding thickness and improves process stability and repeatability.
Uniform powder distribution (direction-independent): Powder delivery is not affected by travel direction, making it suitable for any contour or profile.
Long-focus, long working distance: Supports stable cladding at 19–23 mm standoff, improving accessibility for complex parts.
High-power continuous capability: Designed to support long-duration operation; recommended laser power matching up to ≤ 8 kW.
Copper body + water cooling: Enhanced thermal management for stable performance in high-speed cladding environments.
