Product Description

Laser spot welding is an important way of laser materials processing technology applications, spot welding process is hot conduction type, laser radiation heating the surface, the surface of the heat through the heat transfer based internal diffusion, by controlling the laser pulse width, energy, peak power and repetition frequency and other parameters, so that the work piece to melt to form a specific pool. Because of its unique advantages, it has been successfully applied to gold and silver jewelry processing and micro, small parts welding.

Machine Features :

1). Energy, pulse width, frequency, spot size can be adjusted within a wide range, in order to achieve a variety of welding results. Parameter adjustment lever by a closed cavity, simple and efficient.

2). The British imported ceramic condenser cavity, corrosion resistance, high temperature, high photoelectric conversion efficiency, the condenser chamber life (8–10 years), xenon lamp life of more than 8 million times.

3). The world’s most advanced automatic shading system, eliminating the time to protect the eyes.

4). With 24 hours of continuous work capacity, machine performance and stability, within 1,500 hours of maintenance-free.

5). User-friendly design, ergonomic, long working hours without fatigue.

6). Speed, high efficiency, depth, small deformation, small heat-affected zone, high quality welding, spot clean, efficient and environmentally friendly.


Applications :

Widely used in aviation, aerospace, sporting goods, jewelry, golf club heads, medical equipment, aluminum dentures, instruments, electronics, machining, automotive and other industries, in particular for the fill hole silver platinum titanium stainless steel jewelry accessories point weld lines, precious stones and claw feet by welding.
