Laser cutting machine is a horizontal laser beam emitted by a laser that is transformed into a vertically downward laser beam through a 45 ° total reflection mirror, and then concentrated through a lens to form a very small spot at the focal point. The laser power density at the focal point is as high as 10 ^ 6-10 ^ 9W/cm ^ 2. The workpiece at its focal point is illuminated by a high power density laser spot, which can cause partial high temperatures above 10000 ° C, causing the workpiece to vaporize in an instant. Then, with the assistance of cutting gas, the vaporized metal is blown away, cutting the workpiece into a very small hole. As the CNC machine moves, countless small holes connect to form the shape to be cut. Because the frequency of laser cutting is very high, each small hole connection is very lubricated, and the resulting product has a high smoothness.
Laser welding machine is a new type of welding method. It can complete spot welding, butt welding, overlap welding, seal welding, etc., mainly for the welding of thin wall materials and fine parts. It has high aspect ratio, small weld width, small heat affected zone, small deformation, fast welding speed, flat and beautiful welds, no treatment or simple treatment after welding, high weld quality, no pores, accurate control, small light spots, and high positioning accuracy, eeasy to complete automation. Laser welding machine uses high-energy laser pulses to heat parts of the data in small areas, and the energy radiated by the laser is directed towards the internal diffusion of the data through heat transfer, melting the data and forming a specific molten pool.
The principle of laser welding machine is similar to that of cutting, but the purpose is opposite. Its main secret lies in the power of the laser.
