Jewelry Laser Welding

Jewelry laser spot welding machine is a special equipment specializing in the pores, sandy eyes, and point welding of gold and silver jewelry. Dot welding technology in laser welding is widely used. During the laser welding process, the surface of the processing part is heated, which is transmitted to the internal and spread of the material. Then it controls the width, energy, peak power, and repeat frequency of the laser pulse to melt the workpiece to form a specific melting pool. Due to its unique advantages, it has been successfully applied in the processing of gold and silver jewelry and micro -and small parts of welding.
Product Model: ST-WY150
Laser power: 150W

Features of jewelry laser welding

1. Laser beam can achieve time and energy, which can be processed at the same time, and the welding speed is significantly improved. The processing is completed efficiently and high -quality in a short period of time.

2. The parameter can be adjusted (such as energy, pulse width, frequency, and diameter of light spots), which can achieve welding of different requirements.

3. Use an automatic shading device to protect the eyes of the operator at work.

4. Ceramic laser cavity adopts imported brands, stable and reliable, corrosion resistance, high temperature resistance.

5. The unique YAG crystal cooling method improves the quality of beam and the life of the lamp.

6. 24 -hour work continuously, the performance of the whole machine is stable.

Details of jewelry laser welding

1. Observation microscope

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

2. 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 .

3. Laser optical path

Adopt the British imported brand optical cavity, used to protect the laser source and prolong the service life. Beijing famous brand crystal rod, durable and not easy to damage. 5.

4. 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.

5. 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)

6. Air duct

Continuous output stability to prevent oxidation and blackening of the product during welding, and flexible all-round adjustment of the blowing pipe.

7. Heat dissipation port

There is an exhaust fan at the back to effectively prevent the machine from overheating due to prolonged use.
