Development trend and application of co2 laser marking machine

Laser application fields are very wide. As a direction of laser application, laser welding machine is based on the combination of traditional processing technology and modern laser technology.

Because of the high power density and fast energy release of laser welding, the processing efficiency is higher than that of the traditional method, and the laser welding processing has more superior processing characteristics than the traditional processing. Laser welding is to use high-energy laser pulses to locally heat the material in a small area. The energy of the laser radiation diffuses into the interior of the material through heat conduction, and the material is melted to form a specific molten pool.

Laser welding machine is a new type of welding method, mainly for the welding of thin-walled materials and precision parts, and can realize spot welding, butt welding, stitch welding, sealing welding, etc. , high aspect ratio, small weld width, small heat-affected zone, small deformation, fast welding speed, smooth and beautiful weld, no need or simple treatment after welding, high weld quality, no pores, and can be precisely controlled , The focusing spot is small, the positioning accuracy is high, and it is easy to realize automation.

The traditional process needs to use sheet stacking for welding, and laser welding does not need to contact the surface of the processed item during the entire process, so the laser processing process has advantages that traditional welding methods cannot match.

In order to improve the precision of welding, it is necessary to continuously upgrade the laser welding machine, which makes the laser welding technology more and more widely used in the field of micromachining. The defects of laser welding have gradually replaced traditional processing methods.
