Laser Welder Jewelry

Specially used in jewelry industry metal welding laser equipment, with high precision, low loss, super fast and other advantages. It does not cause any damage to the internal structure of the workpiece and ensures the integrity of the workpiece. The protective gas output ensures that the welded joints are beautiful and will not be oxidized and discolored. It is widely used in the processing of gold and silver jewelry and the welding of micro and small parts.
Product Model: ST-WY150
Laser power: 150W

Features of laser welder jewelry

1. The high performance laser power source developed by our company enables high individual pulse energy, low power, very low heat impact, and no heat during welding.

2. Automatic shading system is used to eliminate damage to eyes during working hours.

3. No filler solder, fast welding speed, high quality, reliable joints, minimal deformation of the workpiece, small heat affected area, beautiful shape, welding joints welding is non-polluting, efficient and environmentally friendly.

4. Ceramic concentrated cavities imported from England are used to ensure high reliability and performance of the equipment. With 24-hour continuous working capacity, the whole machine works stably and maintenance-free for 10,000 hours.

5. The unique YAG crystal cooling method improves beam quality and Xenon lamp life, thus reducing the cost of use.

6. Energy, pulse width, frequency, spot size, etc. can be adjusted over a wide range to achieve various welding results. The parameters are adjusted by a control rod in the enclosed chamber, which is simple and effective.

Details of laser welder jewelry

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.

Advantages of laser welder jewelry

1. Ergonomically designed to meet the jewelry industry's requirements for exquisite and stable performance, suitable for long time continuous work.

2. Large part space, easy to place tools and fixtures.

3. The working area is easy to clean and the welding chips are easy to collect.

4. Adjustable LED light brightness for clearer observation of the welding area.

5. Finer laser spot to meet the needs of fine welding.

6. 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 welder jewelry 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 jewelry, medical parts, watch hairsprings, integrated circuits, various small heat-sensitive parts for precision welding, electronics, communications, machinery, automobiles, military industry, gold jewelry and other industries.
