Presentation of the equipment's characteristics

The Greenstone GST-HD Series High-Speed Laser Cladding Optics Head is a professional-grade coaxial powder laser cladding (LMD/DED) processing head engineered for high-deposition, high-travel-speed cladding and fine deposition applications. Built to meet real industrial demand for productivity and repeatability, the GST-HD head supports up to 8 kW laser power, making it suitable for high-speed cladding tasks where stable energy delivery and powder feeding consistency are critical. The head is designed to be compatible with mainstream laser sources—including fiber lasers and semiconductor (diode) lasers—and supports common fiber interfaces QBH / QD / LLK, helping integrators and end users reduce integration time and cost.

For high-speed manufacturing and remanufacturing, customers need a cladding head that can run continuously, maintain melt-pool stability, and resist dust and powder contamination. The GST-HD series addresses these challenges with an IP65 sealed structure, internal dual water-cooling for thermal stability and optics protection, and a ring-structure cladding nozzle optimized for high-speed processes. It is widely applicable to wear-resistant overlay, corrosion-resistant coating, surface strengthening, and fast build-up deposition where cycle time and cladding efficiency directly affect production output.

processed samples

• Designed for high-speed cladding with high powder throughput
The GST-HD uses a ring-structure powder nozzle designed for high powder delivery, supporting stable material feeding during high-speed laser cladding where conventional nozzles may struggle to maintain consistent deposition.

• Up to 8 kW power capacity for high-efficiency production
With models rated at 6 kW and 8 kW, the GST-HD series targets high-demand industrial applications that require faster processing, stronger bonding quality, and stable performance during long operating cycles.

• IP65 sealed industrial protection for dusty workshops
A fully sealed IP65-rated structure helps protect the optics head from dust and powder contamination—reducing maintenance frequency and improving long-term reliability in real factory environments.

• Coaxial powder feeding improves powder utilization and bead uniformity
The coaxial powder delivery method enhances powder capture efficiency and supports more uniform cladding bead formation, especially important for automated production lines and consistent batch processing.

• Internal dual water-cooling extends optical component lifespan
The internal dual water-cooling system stabilizes thermal conditions and helps extend lens and optics life, supporting continuous operation and lowering total operating cost.

• Multiple nozzle options + optional CCD monitoring interface
Supports multiple nozzle configurations and offers CCD interfaces (Type-C / Type-CS) for melt-pool observation and process monitoring—useful for process validation, training, and quality control.

• Broad laser compatibility for easier system integration
Standard support for QBH / QD / LLK interfaces makes the head easier to integrate with common laser sources and automation platforms (robot, gantry, CNC), matching practical market requirements.
