EHLA Pro Coaxial Annular Powder Feeding Nozzle for Ultra-High-Speed Laser Cladding
Presentation of the equipment's characteristics
The Ultra-High-Speed Coaxial Annular Powder-Feeding Laser Cladding Nozzle is purpose-built for high-precision laser cladding on demanding, tight-tolerance components. Engineered for stable coaxial powder delivery, it produces a highly controlled annular (ring-shaped) powder stream that converges accurately at the deposition zone—supporting consistent melt pool behavior and repeatable coating formation.
Constructed from high thermal conductivity copper (purple copper), the nozzle offers excellent heat dissipation, improving thermal stability during continuous cladding. Its fine and stable powder output helps form dense cladding layers with refined microstructure—ideal for precision surface enhancement, remanufacturing, and repair of high-value parts.
By improving powder focusing performance and spot alignment, the nozzle enhances powder utilization efficiency, reduces common defects (such as porosity, surface waviness, and direction-related inconsistencies), and supports reliable results even on complex contours. For production environments where quality, repeatability, and process stability matter, this nozzle is a high-performance solution for modern laser cladding systems (up to 3 kW).
Stable coaxial powder feeding process: Minimizes defects such as pores, waviness, and directional inconsistency for cleaner, more uniform coatings.
Excellent powder stream focusing: Precisely matches the powder focal spot to the laser spot, maximizing powder utilization and deposition efficiency.
Adaptive deposition thickness control: Helps prevent uneven cladding thickness, improving consistency and process stability.
Direction-independent, uniform powder distribution: Powder delivery is not affected by travel direction, enabling reliable cladding on any contour or geometry.
Copper body for superior heat dissipation: Enhances thermal management and supports stable operation in high-speed cladding applications.
