Figure 4-1 Schematic diagram of the laser cutting head of 4.2 Laser Cutting classification and its mechanism. Vaporization: the workpiece in the laser under rapid heating to the boiling point, part of the material turned into steam Yat go, and part of the material for the ejecta from the cutting seam at the bottom of blown away. The cutting mechanism of the required laser power density is 108W / cm2, about, is the molten material cutting ※ melting cutting: laser workpiece is heated to molten state beam coaxial argon, helium, nitrogen auxiliary gas flow of molten material from the cut cracks blow. Melting cutting the required laser power density generally about 107W/cm2. Melting cutting oxygen to help: metal laser rapid heating to ignite more severe oxidation reaction (combustion) emit a lot of heat and oxygen, but also heats the next layer of metal, metal continued oxidation, and with the gas pressure to oxide from shear cracks blow. However, as a kind of new rising technology, cost of remote control china laser pointer is considerably higher than other products.
Power input is much larger than the rate of heat conduction, convection and radiation cooling material surface vaporization and the formation of holes (Figure 2-1), the hole of the metal vapor pressure and the static surface tension of the surrounding liquid formation of dynamic equilibrium, the laser through the hole direct to the bottom of the hole. 2) the laser deep welding process parameters * the critical power density: deep penetration, the power density must be greater than a certain value, can cause pinhole effect. This value, called the critical power density ※ laser deep penetration welding of: laser deep penetration deep penetration with the laser output power density is closely related to the function of power and spot diameter. Remote control green laser pointer locates the target more accurately and flexibly.
The laser processing using a laser beam projected onto the thermal effect of the surface to complete the processing, including laser welding, laser cutting, surface modification, laser marking, laser drilling and micromachining. Materials for a variety of laser beam processing, such as drilling, cutting, scribing, welding and heat treatment. The laser can adapt to any material processing and manufacturing, in particular, plays an irreplaceable role in a number of special precision and requirements, special occasions and special materials processing and manufacturing. Laser Processing Overview and prospects for development to review the scientific and technological inventions of the 20th century, a significant impact on human society. Remote control china laser pointer also contains Ratio Frequency(RF) technology.
