Laser Welding Stainless Steel

The special equipment for jewelry laser welding is equipped with a special microscope to facilitate the observation and positioning of the operator. By controlling laser parameters such as the width of laser pulse, energy, peak power and repetition frequency, the workpiece is melted and a specific molten pool is formed with good welding effect.
Product Model: ST-WY150
Laser power: 150W

Laser welding stainless steel features-Suntop

Features of laser welding stainless steel

1. The use of British imports of ceramic concentrator cavity, corrosion resistance, high temperature resistance, high photoelectric conversion efficiency, concentrator cavity life (8-10 years), xenon lamp life of more than 8 million times.

2. equipped with liquid crystal eye protection gate, light gate will work accordingly with the laser light out and off light, to achieve laser welding jewelry flash when the laser shield the laser, laser off light transmission, to protect the operator's eyes from the laser flash and feel uncomfortable feeling.

3. installation of argon gas protection device, this function effectively protects the welding position in the welding process is always protected by argon gas, always maintain the original color of the metal, to ensure the quality of welding.

4. special increase in head cushion and arm pad, long time operation without arm and neck pain phenomenon.

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

6. 24-hour continuous working capability, stable working performance of the whole machine, maintenance-free within 10000 hours.

Details of laser welding stainless steel

1. Observation microscope

Adopt domestic 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 extend the service life. Beijing famous brand crystal bar, strong and durable not easy to damage. 5.

4. laser xenon lamp

Using the top domestic brand original xenon lamp.

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

Xenon lamp is the power supply for the laser, when the xenon lamp is used up, replace with a new one.

5. Joystick

Users can also adjust the position of the cursor and set parameters by moving the joystick while performing welding work. (Emergency top/joystick/brightness)

6. Air Duct

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

7. Heat dissipation port

The back side is equipped with an exhaust fan to effectively prevent the machine from overheating due to prolonged use.

Advantages of laser welding stainless steel

1. Ergonomic design of the whole machine, professional appearance design, imported core components, stable performance, suitable for long-term continuous work.

2. The internal space is large, which is convenient for placing laser spot welding tools and fixtures.

3. The working area is equipped with an electric focusing device, and the laser spot welding parameter adjustment is switched on, making it easier to use.

4. Install the fume filter and welding shavings recovery box, which are easy to replace, easy to clean and recover precious metal welding shavings.

5. The brightness of the LED light can be adjusted to observe the workpiece without shadow, and the welding area can be observed more clearly.

6. High magnification beam expansion system, to obtain finer light spots, to meet the needs of fine laser spot welding.

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 welding stainless steel 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.
