Aluminum Laser Welder

Mainly used in gold and silver jewelry to fill holes and spot welding trachoma, laser spot welding is one of the important aspects of the application of laser material processing technology, spot welding process is heat conduction type, that is, laser radiation heating the surface of the workpiece, the surface heat through heat conduction to the internal diffusion, through the control of the laser pulse width, energy, peak power and repetition frequency and other parameters, so that the workpiece melting, the formation of a specific melt pool.
Product Model: ST-WY150
Laser power: 150W

Aluminum laser welder features-Suntop

Features of aluminum laser welder

● Energy, pulse width, frequency, spot size, etc. can be adjusted within a large range to achieve a variety of welding effects. The parameters are adjusted by the control rod in the closed chamber, which is simple and efficient.

● It adopts ceramic concentrating cavity imported from the UK, which is corrosion-resistant, high-temperature-resistant, and has high photoelectric conversion efficiency.

● Adopt the world's most advanced automatic shading system, which eliminates the irritation to the eyes during working hours.

● With 24-hour continuous working capability, the whole machine has stable performance and is free of maintenance within 10,000 hours.

● The unique YAG crystal cooling method improves the beam quality and the life of the xenon lamp, reducing the usage.

●Argon protection device can be installed, this function effectively protects the welding position from argon protection during the welding process, keeps the original color of the metal, and ensures the welding quality.

Details of aluminum laser welder

1. Observation microscope

Adopt the domestic top high precision microscope (10×/20 times) 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 British original imported Morgan brand optical cavity, to protect the laser source and extend the service life.

Using Beijing famous brand crystal rod, CAS design, durable and not easy to damage.

4. laser xenon lamp

Adopt Chinese famous brand original xenon lamp.

Life: 8 million times, for example, 8 hours a day, a light can be used for 6-12 months.

Xenon lamp is the power source of the laser. Xenon lamp is used up, a new one on the line.

5. Joystick

Users can also move the joystick to adjust the cursor position and set parameters while welding. (Emergency top/joystick/brightness)

6. LED light

360 ° LED light, all-round lighting, you can adjust the brightness of the LED light according to the comfort of the eyes, so that the work is easier.

7. Air duct

Continuous output stability to prevent oxidation and blackening of products during welding, flexible and fully adjustable welding torch.

8. Exhaust fan

The back side is equipped with an exhaust fan, which can effectively prevent the machine from overheating due to prolonged use. There is water cooling system inside the machine.

Advantages of aluminum laser welder

1. Ergonomic design of the whole machine, suitable for jewelry laser welding industry, stable performance, suitable for long time continuous work needs.

2. Large internal space, convenient for laser spot welding tools, fixtures placement.

3. Laser welding space is installed with fume filter for easy replacement, as well as welding chip recycling box for easy cleaning and gold welding slag recycling.

4. Adjustable high brightness LED ring type shadowless lamp, observing workpiece without shadow, with high definition body type parallel light path microscope, laser welding position is clearly observed.

5. No need to fill the solder, high welding speed, reliable joints, small deformation of the workpiece, beautiful molding.

6. Fast speed, high efficiency, large depth, small deformation, small heat-affected zone, high welding quality, non-polluting welding joints, high efficiency and environmental protection.

Laser Welding vs TIG Welding

● Deformation

Laser welding has a small heat-affected zone and little deformation; tig-arc welding is prone to deformation.

● Welding spot

Laser welding spot is fine, spot can be adjusted; TIG welding spot is large, not fine.

● Perforation

Laser welding is not easy to perforate, can be accurately controlled; argon arc welding arbitrary perforation, energy can not be controlled.

● Safety

Laser welding irradiation light is almost harmless; tig-arc welding ultraviolet light, there is radiation.

Aluminum laser welder application

Application materials

Mainly used for hole filling spot welding of gold and silver ornaments, also can be used for cold welding of high alloy steel, hot forged high alloy steel, nickel tool steel, high-grade steel, copper alloy, beryllium copper, high toughness aluminum alloy, gold, silver and other metal materials.
