The principle of laser welding:

Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. Laser welding is one of the important aspects of the application of laser material processing technology. In the welding process, the surface of the workpiece is heated by laser radiation, and the surface heat diffuses to the interior through heat conduction. By controlling parameters such as the width, energy, peak power and repetition frequency of the laser pulse, the workpiece is melted to form a specific molten pool. Due to its unique advantages, it has been successfully widely used in precision welding of micro and small parts.

The main feature of this process is non-contact welding, and there is no stress and deformation caused by external force; because the heating time is only a few milliseconds, the thermal effect on the material is only limited to the laser focus spot, and the welding heat affected zone is very small; usually multi-point At the same time, the welding technology can reduce the influence of welding deformation on the performance of optoelectronic devices as much as possible; the welding process is measured in milliseconds, and has very high production efficiency, making mass production possible.

QCW Quasi Continuous Fiber Laser Welding Machine

Fly laser quasi-continuous fiber laser welding machine is a laser welding equipment that uses imported quasi-continuous (QCW) fiber laser as the light source. Micro laser welding. The laser has extremely high photoelectric conversion efficiency, and its power consumption is almost 1/10 of that of traditional laser welding equipment, and the annual electricity bill is reduced from 30,000 to 3,000. The equipment is highly reliable, requires almost no maintenance, and does not need to replace accessories for xenon lamps and laser rods. At the same time, this equipment is a new generation of precision laser welding products with air cooling, compact structure, and occupies only 1/4 of the traditional YAG laser welding machine, which is easy for production line layout or automation integration.

Fly laser laser welding advantages:

1: Laser welding has high speed, high precision and small heat affected area

2: The welding seam of the solder joint is beautiful, almost no post-processing is required, and a lot of cost is saved

3: There is no physical contact during the welding process, and non-contact long-distance welding is implemented, which has great flexibility. Suitable for welding of complex spaces and complex welds

4: Computer control, which is conducive to automatic integration, high production efficiency

5: Micro welding is possible. After the laser beam is focused, a small spot can be obtained, and it can be precisely positioned, which can be applied to the group welding of micro and small workpieces in mass automatic production.

6: Suitable for composite welding of dissimilar materials, such as: aluminum, nickel, copper, stainless steel, zinc, carbon steel, titanium, etc.

7: After the laser is focused, the power density is high, and the aspect ratio of 6:1 can be up to 10:1 during high-power welding

8: The laser passes through the electromagnetic field, and the beam will not deviate; the flying radium laser can be welded in vacuum, air and a certain gas environment, and can be welded through glass or materials that are transparent to the beam

9: The laser beam can realize the beam splitting according to time and space, and can perform multi-beam simultaneous processing and multi-station processing, which provides conditions for more precise welding.
