[0002] Laser cutting is a technology that uses a focused high-power density laser beam to cut materials. It is a type of thermal cutting. Laser cutting is divided into laser gasification cutting, laser melting cutting, laser oxygen cutting, laser scribing and controlled fracture. Among them, the commonly used gases for laser cutting machines include oxygen, nitrogen, inert gas, air and carbon dioxide.
