Laser cutting machine and laser welding machine are to rely on laser to complete the processing tasks, but the functionality of the two are very different. So, what is the difference between the two? The following high-energy laser to tell you about!

Laser cutting machine is the level of the green laser pointer beam emitted by the 45 ° total reflection mirror into a vertical down the laser beam, after the lens gathered in the focus at the focus into a very small spot in the spot at the focus of the laser And the power density is as high as 10 ^ 6 ~ 10 ^ 9W / cm ^ 2. In the focus of the workpiece by high power density laser beam shine, will occur more than 10000 ° C part of the high temperature, so that an instant vaporization of the workpiece, and then cooperate to help cut the gas will vaporize the metal blown away, so the workpiece cut through Into a very small hole, with the movement of CNC machine tools, numerous small holes connected to become cut to shape. Because the frequency of laser cutting is very high, so each hole is very smooth interface, cut out of the high quality of goods.

However, the high power laser pointer welding machine is a new welding method, mainly for thin-walled materials, fine parts of the welding, to complete the spot welding, butt welding, stack welding, sealing welding, aspect ratio, weld width, heat The welding area is small, the deformation is small, the welding speed is fast, the welding seam is flat and beautiful. After welding, it needs no treatment or simple treatment. The welding seam has high quality and no stomata, can be controlled accurately, small spot of gathering, high positioning accuracy and easy completion. automation. It uses high-energy laser pulse on the data within a small area of the partial heating, the energy of laser radiation through the heat transfer to the internal diffusion of data, the data will melt into a specific pool.

I believe that through the above description, we face the two laser equipment will have a certain understanding! In fact, the principle of laser welding machine and the cutting of similar principles, but to achieve the purpose is the opposite, the most important secret lies in the power of the laser. According to experience, the two are in fact able to complete the symbiotic above a machine, just write a slightly different program, called the burning laser pointer power is different.
