High Precision 200W Jewelry Spot Laser Welding Machine for Gold and Silver Jewelry


DG-SW200 jewelry laser welding machine is specially developed for laser welder of jewelry by Dong Gu and mainly used in perforating and spot welder of gold and silver jewelry. It is of touch screen type, adopting new style power source, elaborating operation, and optimizing the optical path, with high photoelectric conversion efficiency, high stability, small size, high configuration and other characteristics. The laser spot welding is an important aspect of laser process technology application. The spot welding process is thermal conduction, i.e. the laser radiation heats the surface of work piece, and 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. It is mainly used in the welding process of jewelry metal material, with elegant and solid welding spot, small heat-affected zone, high efficiency and low cost. It gains a wide use in microelectronics, aerospace equipment, optical communication equipment, electric vacuum devices, instruments, mechanical and electrical products, automotive manufacturing and other industries.

 Why our fiber laser marking machine is best? 
1. Producing higher quality beam,higher photoelectric conversion, the marking quality will be more finer and higher precision
2. Small Size of water chiller.
3. No maintenances laser source(100,000 hours service time), easy to adjust focus.
4. low operation cost (low power consumption)
5. Maintenance free without routine replacement of consumables
6. Easy to use by unskilled operator

I. Ceramic converging cavity is imported from the Britain. It is corrosion resistant and high temperature resistant , and has 8-10 years service life.

II. High production efficiency and high welder speed, realizing automatic mass production on the production line

III. The laser head can be adjusted for 360 degree

IV. The size of the light spots can be adjusted

V. The work bench can be moved in two dimensions
