As one of the hot cutting, laser cutting is widely welcomed. In real work, laser cutting can be achieved in several ways. This involves several working principles of laser cutting, and the cutting effect obtained is also different.
A technology of laser vaporization cutting is to use laser beam to heat the workpiece. Because of its high energy, it can make the temperature rise rapidly, and the material will begin to vaporize. When steam is ejected, there will be incision formation on the material. This cutting needs a lot of power and power density to complete, most of which are used in cutting process of very thin metal and non-metallic materials.
The other is laser melting and cutting, heating the metal and melting it. Then the liquid metal is discharged by the strong pressure of the gas, and the incision is formed. Because it does not need to be completely vaporized metal, so the consumption of energy consumption is also reduced a lot, generally in some not easy to oxidize material or active metal cutting use more.
Another is laser oxidation cutting, using laser as a heat source, and oxygen and other active gas as cutting gas, through the joint action of both in the formation of the metal in the incision. In the process, there will be a lot of heat release, which will also help to save energy consumption.
In addition to the above three laser cutting modes, laser scribing and controlled fracture can also cause material to be disconnected, thus obtaining the required size requirements.
