The cutting process of laser welding and fiber laser cutting machine are two completely different working principles.

Laser cutting uses high temperature to immediately melt metal and blow away molten iron slag to form a cutting seam. Laser welding is a welding process that uses laser action to produce instantaneous melting on the metal surface to connect metals.

1. Laser welding is used for sealing welding of the shell of microelectronic equipment. There is no need to worry about damage to the instrument due to heating. After laser welding, the precision laser welding machine manufacturer can weld the workpiece without air holes according to the process requirements, so as to realize the fully sealed welding of the micro equipment shell.
2. Laser precision welding is used to weld the original microcircuit. Laser precision welding is suitable for the welding of microcircuit components, mainly including the connection of lead wires and printed circuit boards, the contact connection of lead wires and silicon plates, the soldering of thin wires and films, and the connection of integrated circuits and coplanar leads and printed circuit boards.

 Laser welding for precision parts welding uses a laser beam focused by a high-power coherent monochromatic photon stream as a heat source for welding. This welding method usually includes continuous power laser welding and pulsed power laser welding. The advantage of laser welding is that it does not need to be carried out in vacuum, but the disadvantage is that the penetration is not as strong as electron beam welding.
Laser welding of precision parts can carry out accurate energy control, so it can realize the welding of precision micro equipment. It can be applied to a variety of metals, especially to solve the welding of some difficult-to-weld metals and dissimilar metals.

The production of lasers for welding precision parts: After exciting the material, it will produce a beam of the same wavelength, frequency and direction.

The characteristics of laser welding precision parts: it has the characteristics of good monochromaticity, good directionality and high energy density. After the laser is focused by a transmission or reflector, an energy beam with a diameter of less than 0.01mm can be obtained, and the power density is as high as 1013W/cm2. It can be used as a heat source for welding, cutting, drilling and surface treatment. . The materials that generate laser light are solid, semiconductor, liquid, gas, etc. Among them, YAG solid-state lasers and CO2 gas lasers are mainly used for industrial processing, such as welding and cutting.
