Also known as channel letter laser welding machine uses high pulsed laser power to weld the target. By using laser to pulse discharging on the xenon lamp, a lightwave with certain frequency and pulse width will form & then radiate to Nd:YAGcrystal using optical cavity. A 1064nm pulse laser will output after the crystal is being resonated, weld the target after being expanded, reflected and focused.

Product’s Features

The principle of the laser welder is based on high-energy laser focus point welding technology. It can effectively handle small area welding and make up the shortcomings of the traditional soldering and welding technology. Avoiding heat strain and post-processing stage and save a lot of time.

1. It has red pointer for fast positioning, CCD monitoring & microscope.

2. Moveable working platform and laser cavity are suitable to the letter with any size and any shape.

3. High processing speed, fixed focus position with rotary bearing level make focus easier even without CCD or microscope.

4. Little heat deformation effect and heat affectedzone

5. Capable of doing partial heat treatment on letters.

6. Suitable to process complex and tiny parts.

7. Low processing noise and no pollution.

8. Ultra-fine rotary bearing level makes corner welding easier even without changing letter position.

9. Advance processing method greatly improves the letter quality.

10. Our own high peak laser power make can easily achieve aluminium letter welding compare to other brands.
