Custom GST Series QCW Fiber Laser Welding Machine (Quasi-Continuous Wave / CW Mode)
Presentation of the equipment's characteristics
The Greenstone GST Series QCW Fiber Laser Welding Machine is a high-efficiency quasi-continuous wave (QCW) fiber laser system designed for precision welding where strong peak power and stable energy output are required. Built as a compact, low-maintenance alternative to traditional lamp-pumped YAG solutions, the GST QCW platform supports CW/QCW operating modes to cover spot welding, seam welding, micro-welding, drilling, and fine cutting tasks in production. With stable power delivery across a wide dynamic range and flexible control interfaces, it is ideal for manufacturers seeking higher yield, better consistency, and lower total operating cost.
QCW High Peak Power for Strong Penetration: Supports up to 1500W / 3000W peak power for fast, clean weld formation and improved processing capability on demanding joints.
CW + QCW Dual Mode Flexibility: One machine covers both continuous and quasi-continuous applications, improving equipment utilization for multi-process factories.
High Electro-Optical Efficiency & Cost Saving: More efficient energy conversion (claimed >30%) helps reduce electricity consumption and operating cost.
Stable Energy & Power Output: Consistent pulse power/energy within the laser power dynamic range improves weld repeatability and reduces scrap.
Compact, Industrial Design: Space-saving footprint and robust integration for workshop environments.
Low Maintenance, Long Service Life: Designed for reduced consumables and minimal maintenance during normal service life.
Industrial Connectivity: Supports analog control + RS-232 + RJ45 network, making it easier to integrate into automation lines, PLC/SCADA, or MES-linked production.
