Product Description

Optical Fiber automatic Laser Welding Machine for alloy steel soldering 400W

QA-400A is a automatic laser welding machine  through the fiber optic cable transmission. The laser source is still NG:YAG.
The optical fiber laser soldering system is equiped with a golden sealed laser cavity, red diamond rod, 2 Xonen lamps etc.
When laser radiation heats the surface of work-piece, the surface heat diffuses to the interior through thermal conduction and melts the work piece by controlling the width, energy, peak power and repeating frequency of laser pulse to form specific molten pool.
After the fiber optical transmission, the laser beam quality will be much better and suitable for precise laser welding.


1. Able to work for 24 hours continuously; stable performance; free of maintenance in 10,000 hours.
2. Human-based design accords with ergonomics, avoiding fatigue after long time working.
3. High speed, high efficiency, deep enough, slightly deformation, small heat effect area, high welding quality, pollution free, environmental friendly.
