1-1 Prospect of AD metal letters/signage welding 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 (8-10 years color preservation), corrosion proof, rain-proof, and
spontaneous combustion proof and some other good features. AD metal letters are made of
stainless steel, aluminum, copper or other metal sheet being cut, polished, hemmed, and
welded. The core feature of AD metal letters is being rustproof, with long life span and
dimensional looks. It’s widely used in LED illuminated billboard, exterior/interior signs,
branding, door plate and etc.
Regular combination and fixing of metal letters are done via glue, rivets or soldering, but all
of them have big defects. 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.
However, laser welding technology makes two metal sheets become one only by a few
melting spots. From any aspect, laser welding is the best solution and the greenest.
1-2 Application:
Applied for the welding of various metal letters, LED illuminated letters, customized metal
signage, and exterior billboards.

2. Adjustable working table allows welding from small size to big size of work piece
3. Fast working speed; professional jig ensures the focus fixed and makes welding
easier without using CCD or microscope
4. Slight distortion and affect by heating.
5. Capable of partial heating process.
6. Able to deal with complex, profiled, or tiny letters.
7. Low noise and no pollution.
8. Ultrafine positioning rod makes the welding of tiny corner easier without changing
spot position
9. New metal processing technology brings higher quality of end products.
