Fully Submersible Underwater Laser Head
The JX-ULH Submersible Underwater Laser Cutting & Welding Head is engineered for reliable laser processing in submerged industrial environments. Designed for underwater operation up to 35 meters, the fully sealed structure ensures dependable waterproof performance and long-term durability.
Equipped with a pneumatic mechanical isolation valve, the system prevents water backflow when the laser is inactive, protecting internal optical components. The head supports both underwater laser cutting and welding applications, offering flexible operation across marine repair, offshore engineering, and hydropower maintenance.
Compatible with QBH, QD, LOE, Q+, and QP fiber interfaces, and integrated with a high-definition CCD monitoring system, it enables precise and controlled underwater laser processing with real-time visual feedback.
