Long-Focus Water-Cooled Coaxial 4-Stream Laser Cladding Nozzle (Large Spot & Long Standoff)
Presentation of the equipment's characteristics
The Long-Focus Water-Cooled Coaxial 4-Stream Laser Cladding Nozzle from Greenstone is engineered for high-efficiency DED/LMD laser cladding on large components where long working distance, high deposition productivity, and stable coating quality are essential. Compared with conventional coaxial annular and 3-point designs, this 4-stream coaxial nozzle delivers a larger powder spot and a longer standoff, making it especially effective for high-speed cladding and large-area surface processing.
Its optimized coaxial powder delivery forms a concentrated, controllable powder focus that can be precisely matched to the laser spot. When paired with high-power, large-spot laser sources, the nozzle helps achieve higher cladding efficiency while maintaining stable melt pool behavior and consistent layer formation. The water-cooling structure supports long-duration operation and contributes to extended service life, reducing downtime and improving production continuity in demanding industrial environments.
With a 30–31 mm working distance and a 2–4 mm powder spot size, this nozzle is well-suited for large workpiece repair, remanufacturing, and surface strengthening—including wear-resistant overlays, corrosion-resistant coatings, and heavy-duty component restoration where process stability and repeatability matter.
Stable coaxial powder-feeding process: Reduces common defects such as porosity, waviness, and directional inconsistency.
Excellent powder stream focusing: Enables precise control to match powder focus with the laser spot, maximizing powder utilization.
Adaptive deposition thickness control: Helps prevent uneven cladding thickness, improving process stability and coating consistency.
Uniform powder distribution (direction-independent): Powder delivery is not affected by travel direction, suitable for complex contours.
Long-focus, long working distance: 30–31 mm standoff improves accessibility and stability on large parts.
High-efficiency with high-power lasers: Designed to work effectively with high-power, large-spot lasers for faster cladding output.
Water-cooled durability: Supports continuous operation and contributes to longer service life.
