Greenstone GST-LR High-Power Coaxial Powder Laser Cladding Head (IP65, Wide-Beam, Dual Water-Cooled, Up to 12 kW)
Presentation of the equipment's characteristics
The Greenstone GST-LR Series High-Power Laser Cladding Optics Head is a heavy-duty coaxial powder laser cladding (LMD/DED) processing head designed for medium-to-high power laser surface engineering where stability, deposition efficiency, and long-duty operation are essential. Built to handle demanding production requirements, the GST-LR series supports laser power up to 12 kW, making it ideal for wide-beam cladding, high-throughput coating, and industrial remanufacturing applications. The head is compatible with mainstream laser sources—including fiber lasers and semiconductor (diode) lasers—and supports common fiber interfaces QBH / QD / LLK, which helps integrators shorten commissioning time for robot, gantry, and CNC-based cladding systems.
In real-world manufacturing, customers often face challenges such as high heat load, powder contamination, unstable melt pool, and frequent maintenance. The GST-LR series addresses these needs through an IP65 sealed structure, internal dual water-cooling, and a coaxial airflow protection design that helps keep optics cleaner during continuous operation. By combining different optical paths and multi-channel nozzle configurations, the GST-LR series can support a range of cladding modes—from standard overlays to 3D deposition (DED-style build-up)—while maintaining consistent process performance and repeatable coating quality.
• High-power capability up to 12 kW for industrial productivity
GST-LR is engineered for demanding, high-power laser cladding operations (10 kW / 12 kW models), enabling faster processing and stable cladding output in real production environments.
• IP65 sealed design for powder & dust protection
The fully sealed IP65 structure improves reliability in dusty workshops and powder-fed cladding environments, helping reduce downtime and maintenance frequency.
• Multi-nozzle / multi-channel powder delivery improves deposition efficiency
The GST-LR supports multiple powder-feeding/nozzle combinations, increasing powder utilization and deposition stability—especially valuable for wide-beam cladding and high-throughput coating lines.
• All-copper optics/mirror design for high-power stability
An all-copper mirror/optics design helps enhance thermal stability under high power, supporting consistent melt pool behavior and repeatable coating results.
• Dual internal water-cooling + coaxial airflow protection extends optics life
The internal dual water-cooling system manages heat effectively, while coaxial airflow protection helps reduce lens contamination—improving long-term optics lifespan and process consistency.
• Flexible optics configuration for wide-beam cladding and 3D deposition
Optional collimation and focusing lens sets support different process requirements, from wider track overlays to build-up deposition and complex remanufacturing tasks.
• Optional CCD interfaces for monitoring & process control
Supports Type-C / Type-CS CCD interfaces for observing the melt pool, assisting process development, quality control, and operator training.
