What is the relationship between the quality of the laser welding machine and the beam mode？

The laser welding machine uses high-energy laser to perform non-contact welding on the weld seam, which greatly improves the work efficiency and quality. However, the quality of the laser welding machine is affected by many factors, among which the light speed mode of the laser welding machine undoubtedly affects a more powerful factor. What is the relationship between the quality of the laser welding machine and the beam mode?

When the laser welding machine is performing welding work, the main function is the laser power density value. Different materials have critical power density thresholds. In order to weld, the power of the laser welding machine must exceed this critical threshold, so that the material can be melted and the welding effect can be achieved.

 
The relationship between beam mode and welding quality is that the beam mode determines the energy distribution of the focus. When the laser beam of the laser welding machine is the base model, the depth and aspect ratio of the weld 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 larger the value of the beam focusing characteristic parameter K, the smaller the aspect ratio of the weld and the worse the quality. The power density that makes the material form small holes is not only related to the average power density, but also mainly depends on the power density. Power density is also related to cross-sectional energy distribution.

 
The relationship between the quality of the laser welding machine and the beam mode is that the mode characteristics of the beam include the beam quality of the laser beam, the beam mode and the cross-sectional energy distribution of the beam. The quality of the laser welding machine affects the stability of the beam, and the beam mode is very important for laser processing. When using a laser welding machine to work, be sure to select the light speed mode of the laser welding machine, so as to ensure the normal operation of the welding machine.
