การ หัวฉีดเลเซอร์แบบเคลือบผิวด้วยผงโลหะชนิดวงแหวนแกนร่วมระบายความร้อนด้วยน้ำสำหรับงานเคลือบผิวแบบโฟกัสยาว จาก กรีนสโตน 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 ทองแดงที่มีค่าการนำความร้อนสูง (ทองแดงสีม่วง) 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.

ด้วย long-focus design และ 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.
