YAG Channel Letter Fiber Laser Welding Machine 300W CCD Display For ADs Board

YAG Channel letter laser welding machine 300W CCD display ADs board



Signage-300 Channel letter laser welding machine is a YAG laser soldering machine system. The laser output power can reach 300W, the workpieces will be very steady after welding.

The laser source is NG:YAG laser, use golden laser cavity, Xenon lamps and red diamond rod.

The working principle based on laser high heat energy and focus point of welding technology, effectively handle all small parts of welding, makes up for the traditional argon arc welding technology in repair welding of fine surface. To avoid the thermal strain and post-processing the two threshold, greatly improving the connection strength and quality of the metal or metal signs.





1. Application material: Aluminum, stainless steel, steel plate, iron plate and other metal, galvanized coil and alloy.

2. Red light fast positioning, CCD display, microscope optional.

3. Adjustable working table allows welding from small size to big of work piece.

4. Fast working speed; professional jig ensures the focus fixed and makes welding easier without using CCD or microscope.

5. Slight distortion and affect by heating.

Prospect of laser technology in Ads industry


With the booming of global advertising industry, metal letters has been more and more popular because of its colorfulness, attractiveness, heating-proof, frozen-proof, no deformation, no fadedness , corrosion proof, rainproof, and spontaneous combustion proof and some other good features.

Regular combination and fixing of metal letters are done via glue, rivets or soldering, but all of them have big disadvanges. Metal letters combined by glue always get loose with time goes by, especially at outdoors. Fixing by rivets sounds good, but not good-looking. Soldering is never a green way of fixing metal letters because of the poisoning gas produced when processing. From any aspect, laser welding is the best solution and the greenest.
