Jewelry Laser Welding Machine

Jewelry laser spot welding machine is realized by the laser beam emitted from the laser to achieve high density energy acting on the object to make it achieve precision welding effect. Small thermal deformation, fast welding speed, no porosity, flat and smooth weld seam, beautiful appearance and no treatment and micro-processing after welding are required. During the welding process, the welding effect can be controlled, accurate positioning can be achieved, and fully automatic manipulation is possible.
Product Model: ST-WY150
Laser power: 150W

● Adopt the world's most advanced automatic shading system, eliminating the stimulation to eyes during working hours.

● With 24-hour continuous working capability, the whole machine has stable working performance and is maintenance-free within 10000 hours.

● Humanized design, ergonomic, long working hours without fatigue.

Details of jewelry laser welding machine

1. Humanized design

Adopt the latest European portable mini design, scientific and streamlined mechanical structure, high-grade alloy chassis, anti-static, rust-proof, easy to move and space-saving.

2. Observation microscope

Adopt China's top high precision microscope (10×/20x) for precise positioning and welding process.

3. Control screen

Built-in touch screen control system with high sensitivity and easy parameter setting. Users can set different parameters (current, frequency, pulse...) according to different materials .

4. Laser light path

Adopt the British imported Morgan brand optical cavity, used to protect the laser source and extend the service life.

Adopt Beijing famous brand crystal rod, designed by the 11th Academy of Sciences of China, durable and not easy to damage.

5. Laser xenon lamp

Adopt the top brand original xenon lamp in China.

Lifespan: 8 million times, for example, working 8 hours a day, a lamp can be used for 6-12 months.

Xenon lamp is the power source of the laser, when the xenon lamp is used up, replace it with a new one.

6. Joystick

When the user performs welding work, he can also adjust the position of the cursor and set parameters by moving the joystick. (Emergency top/joystick/brightness)

7. LED light

The user can adjust the brightness of the led light according to the comfort of his eyes.

8. Gas piping

In order to ensure the welding clean, it is necessary to blow argon gas to protect the welding surface.

9. Exhaust fan

There is an exhaust fan at the back to help cooling. There is a water cooling system inside the machine.
