Laser welder for jewelry features-Suntop

Features of laser jewelry welder

1. Imported ceramic concentrating cavity is adopted, with high reflectivity and strong energy. Ultra-long service life, long life of spot cavity (8-10 years), life of xenon lamp is more than 8 million times.

2. The closed workbench has a built-in welding shavings recovery box, which is convenient for cleaning and recycling of precious metal welding slag.

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

4. It has the ability to work continuously for 24 hours, the performance of the whole machine is stable, and it is maintenance-free within 10,000 hours.

5. 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.

Details of laser jewelry welder

1. Observation microscope

China's top high-precision microscope (10×/20 times) is used for precise positioning and welding process.

2. Control screen

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

3. Laser light path

Adopt the Morgan brand optical cavity imported from the UK to protect the laser source and prolong the service life.

It adopts Beijing famous brand crystal rod, designed by the Chinese Academy of Sciences, which is durable and not easy to damage.

4. Laser xenon lamp

Adopt Chinese famous brand original xenon lamp.

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

The xenon lamp is the power source of the laser. When the xenon lamp is used up, just replace it with a new one.

5. Joystick

Users can also adjust the position of the cursor and set parameters by moving the joystick when welding. (emergency top/joystick/brightness)

6. LED lights

360° LED lights, all-round lighting, the brightness of the LED lights can be adjusted according to the comfort of the eyes, making work easier.

7. Duct

The continuous output is stable, preventing oxidation and blackening of products during the welding process, and the torch is flexible and fully adjustable.

8. Exhaust fan

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

Advantages of laser jewelry welder

1. The ergonomic design of the whole machine can work for a long time without fatigue, which is suitable for the jewelry laser welding industry.

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

3. The brightness of the LED light is adjustable, so that the welding area can be observed more clearly.

4. Spot welding, butt welding, lap welding, sealing welding, single-segment straight line in the plane, circular arc and other welding methods.

5. Fast speed, high efficiency, large depth, small deformation, small heat-affected zone, high welding quality, no pollution, 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.

Laser jewelry 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.

Application industry

Widely used in aviation, aerospace, sporting goods, jewelry, golf heads, medical equipment, aluminum alloy dentures, instruments, electronics, machining, automobiles and other industries, especially for hole filling of gold and silver jewelry, spot welding seams, Welding of mosaic parts and claw feet.
