Views：1805Laser cutting is to irradiate the laser beam on the material surface where to be cut, then heat up, melt and vaporize the material, blow away the melt with high-pressure gas to form a hole,and then the beam moves on the material, and the hole continuously forms a cutting seam.
In general thermal cutting technology, except for a few cases that can start from the edge of the plate, most of them need to wear a small hole on the plate, and then cut from the small hole.
Principle of laser perforation
The basic principle of laser perforation is: when a certain energy laser beam irradiates on the surface of metal plate, except that part of it is reflected, the energy absorbed by the metal meltsthe metal itself to form a metal melting pool. The absorption rate of molten metal relative to the metal surface increases, that is, it can absorb more energy and accelerate the melting process of metal.
At this moment, properly controlling the energy and air pressure can remove the molten metal in the molten pool and continuously deepen the molten pool until it penetrates the metal.
In practical application, perforation is usually divided into two ways: pulse perforation and blasting perforation.
