Laser cutting generally has the following uses:
1) Laser vaporization cutting
The high-energy-density laser beam is used to heat the workpiece, so that the temperature rises rapidly, reaching the boiling point of the material in a very short time, and the material starts to vaporize and form vapor. The jetting speed of these vapors is very high, and at the same time as the vapor jets, cuts are formed in the material. The heat of vaporization of materials is generally very large, so a large power and power density are required for laser vaporization and cutting. Laser vaporization cutting is mostly used for cutting extremely thin metal materials and non-metal materials (such as paper, cloth, wood, plastic, rubber, etc.).
2) Laser melting and cutting
In laser melting and cutting, the metal material is melted by laser heating, and then non-oxidizing gas (Ar, He, N, etc.) is sprayed through a nozzle coaxial with the beam, and the liquid metal is discharged by the strong pressure of the gas to form an incision. Laser melting and cutting do not need to vaporize the metal completely, and the energy required is only 1/10 of that of vaporized cutting. Laser melting cutting is mainly used for cutting some non-oxidized materials or active metals, such as stainless steel, titanium, aluminum and their alloys.
3) Laser oxygen cutting
The principle of laser oxygen cutting is similar to oxyacetylene cutting. It uses laser as the preheating heat source and oxygen and other active gas as cutting gas. On the one hand, the blown gas reacts with the cutting metal to cause oxidation reaction and release a large amount of oxidation heat; on the other hand, the molten oxide and melt are blown out of the reaction zone to form an incision in the metal. Since the oxidation reaction in the cutting process generates a lot of heat, the energy required for laser oxygen cutting is only 1/2 of the melting cutting, and the cutting speed is much faster than laser vaporization cutting and melting cutting. Laser oxygen cutting is mainly used for easily oxidized metal materials such as carbon steel, titanium steel and heat-treated steel.
4) Laser scribing and controlled fracture
Laser scribing uses a high-energy density laser to scan the surface of the brittle material, so that the material is heated to evaporate a small groove, and then a certain pressure is applied, and the brittle material will crack along the small groove. The lasers used for laser scribing are generally Q-switched lasers and CO2 lasers. Controlled fracture is the use of the steep temperature distribution generated when the laser groove is carved, which generates local thermal stress in the brittle material and causes the material to break along the small groove.
