Laser welding machine is a new type of welding method. It is mainly used for welding thin-walled materials and precision parts. It can realize spot welding, butt welding, stack welding, seal welding, etc. It has a high aspect ratio, small weld width, and heat-affected zone. Small, small deformation, fast welding speed, smooth and beautiful welds, no post-welding processing or only simple processing, high weld quality, no pores, precise control, small focused light spot, high positioning accuracy, easy to realize automation. It uses high-energy laser pulses to locally heat the material in a small area. The energy of the laser radiation diffuses into the interior of the material through heat conduction, melting the material to form a specific molten pool.
Laser cutting machine is a horizontal laser beam emitted by the laser that is transformed into a vertical downward laser beam through a 45° total reflection mirror. It is then focused by a lens to form a very small spot at the focus. The laser power is focused at the spot. The density is as high as 10^6~10^9W/cm^2. The workpiece at its focus is irradiated by a high-power density laser spot, which will generate a local high temperature of more than 10,000°C, causing the workpiece to instantly vaporize. The auxiliary cutting gas is then used to blow away the vaporized metal, thereby cutting the workpiece into a very small piece. Small holes, as the CNC machine tool moves, countless small holes are connected to form the shape to be cut. Because the frequency of laser cutting is very high, the connection between each small hole is very smooth, and the cut product has a high finish.
The difference between laser welding machine and laser cutting machine
Laser welding machines are used to weld metal, and laser cutting machines are used to cut handicrafts. Although it is difficult to determine the specific difference in internal parameters between the two from the definition and indirection of the two, according to experience, the two can actually achieve symbiosis on the same machine, but the programming is slightly Different, the laser power called is different.
