Laser welding machine uses laser beam to mark permanent symbols on different material surfaces. The effect of marking is to expose the deep material through the transpiration of the surface material, or to "carve" the traces through the chemical and physical changes of the surface material caused by the light energy, or to burn off some materials through the light energy, so as to show the required etched images and characters. It is widely used in Changning factory. It is also called laser welding machine and laser welding machine. According to its operation method, it can be divided into laser mold welding machine (manual welding machine), automatic laser welding machine, laser spot welding machine and optical fiber transmission laser welding machine.
Optical welding is to use high-energy laser pulse to heat part of the data in a small area. The energy radiated by laser is guided by heat transfer The internal laxity of the data forms a specific melting pool after melting the data to reach the intention of welding. Laser marking machine is to use laser beam to mark permanent symbols on different material surfaces. Laser marking machine can be divided into CO2 laser marking machine, UV laser marking machine, green laser marking machine and fiber laser marking machine according to different lasers. Computer control system is the center of control and command of the whole laser marking machine, and also the carrier of software equipment. The laser marking machine should be used in a dust-free environment of 10 ℃ - 35 ℃ as far as possible, and the optical devices should be dry and dust-free. Laser marking machine is mainly used in some occasions with higher precision and precision.
