What Are the Effects of Laser Beam on the Quality of Laser Welding Machine
With the rapid development of China's laser welding industry in recent years, we have been influenced by laser welding machines. Laser automatic welding machine welding technology is a comprehensive technology integrating laser technology, welding technology, automation technology, material technology, mechanical manufacturing technology and product design. As an advanced manufacturing equipment, in today's highly automated, laser automatic welding has begun to integrate into various industries.
Different from the traditional welding equipment, the closed-loop control laser welding machine of Shenzhen Zichen laser does not need to use electrodes, and there is no concern of electrode pollution or damage. Because it is not a contact welding process, the loss and deformation of machines and tools can be minimized. In addition, the energy characteristics of the laser beam of the closed-loop control laser welding machine are high, mainly including the wavelength of the laser beam and the power and power density of the beam. In the production of each laser welding machine, the quality requirements are more stringent, so the quality of this laser welding machine will directly affect the stability of the laser beam?
Laser welding machine plays a major role in welding is the laser power density value. This is because there is a critical power density threshold for different materials. Only when the power density value of the laser beam focus exceeds this threshold, can small holes be formed and deep penetration welding be obtained. This is for wavelength 10.6 M CO2 laser beam is of great significance. Because metal materials strongly reflect laser beams of this wavelength.
When the laser beam is the basic mode, the maximum weld depth and depth width ratio can be obtained. The higher the order of the beam mode, the more divergent the energy distribution of the laser beam and the worse the welding quality. The influence of laser beam with different beam focusing characteristic parameter value K on laser welding quality. The larger the beam K value, the worse the quality and the smaller the depth width ratio of weld. The power density of forming small holes in materials is not only related to the average power density, but mainly depends on the maximum power density, which is closely related to the cross-sectional energy distribution.
The relationship between the quality of laser welding equipment and the beam mode characteristics. The beam mode characteristics include the beam quality, beam mode and cross-sectional energy distribution of laser beam. The beam mode determines the energy distribution of the focus, which has an important impact on laser processing. The quality of laser welding machine affects the beam stability. Let's share it here. The laser welding machine has different cross-sectional energy distribution for the focus with certain power and the same radius. Although the average power density is the same, the maximum power density is not the same.fqj
