SHFULAI Laser Welding Machines

1. What is a laser welding machine?

The laser welding machine is a device that uses laser beams as a heat source for welding.

2. What is the working principle of laser welding machine?

The working principle of the laser welding machine is to generate a high-energy laser beam through the laser, and then use the optical system (controller, collimating lens, reflective lens, focusing lens, protective lens) to adjust and control the laser beam to focus it on On the welding part (or 0 focal length, or positive focal length, or negative focal length). Under the irradiation of the laser beam, the welding part will be affected by high energy and high temperature, causing the welding materials to melt and fuse together.

3. What are the main components of a laser welding machine?

Laser transmitter, laser welding joint (optical system and mechanical structure), control system, mechanical movement system, cooling system, protective gas, and other auxiliary systems.

4. How are laser welding machines classified according to laser type?

According to the type of laser, laser welding machines are divided into CO2 laser welding machines, fiber laser welding machines, carbon dioxide laser welding machines, semiconductor laser welding machines, etc.

5. What types of laser welding machines does our company mainly produce?

Our company mainly produces fiber laser welding machines. The specific types include handheld laser welding machines, automatic laser welding machines, and robot laser welding machines.

Features of laser welding:
Laser welding is a welding method that uses a high-energy-density laser beam as a heat source. Using laser welding, not only is the productivity higher than traditional welding methods, but the welding quality is also significantly improved. Compared with general welding methods, laser welding has the following characteristics.
1. The focused laser beam has high power density and fast heating speed, enabling deep penetration welding and high-speed welding. Due to the small heating range of the laser (the spot diameter is less than 1mm), under the same power and thickness of the weldment, the welding heat affected zone is small, and the welding stress and deformation are small.
2. Laser can emit and transmit, and can propagate a considerable distance in space with very little attenuation. It can be transmitted and deflected through bending of optical fibers, prisms, etc., and is easy to focus. It is especially suitable for focusing on micro parts in a small area, inaccessible parts, or Welding over long distances.
3. It is non-contact welding, does not require the use of electrodes, and there is no electrode pollution or wear. One laser can be used for different processing on multiple workstations. It can be used for welding, cutting, cladding, alloying and surface heat treatment, etc. One machine has multiple uses.
4. The laser beam does not attenuate much in the atmosphere and can pass through transparent objects such as glass. It is suitable for welding highly toxic materials such as beryllium alloy in sealed containers made of glass. The laser is not affected by electromagnetic fields and can accurately align the weldment. ; There is no X-ray protection and no vacuum protection is required.
5. It can weld materials that are difficult to weld with conventional welding methods, such as high melting point metals and non-metallic materials (such as ceramics, organic glass, etc.). Materials that are sensitive to heat input can also be laser welded. No heat treatment is required after welding, and various materials can be welded. heterogeneous materials.
