Laser welding provides an ideal welding method for enterprises. Nowadays, laser welding is also a powerful new laser technology. PURE-AIR is an environmental protection equipment manufacturer that provides welding fume extractor for laser welding manufacturers, so we know the reason.

According to the different laser output power and energy mode, laser welding is pulse laser welding and continuous laser welding (including high-frequency pulse continuous laser welding); according to the difference of power density displayed on the spot after laser focusing, laser welding can be divided into heat transfer Welding and deep penetration welding are two major categories.

1. The main feature of heat transfer welding is that the power density of the laser spot is small, a large part of the light is reflected by the metal surface, the light absorption rate is low, the welding penetration is shallow, and the welding speed is slow. It is mainly used for thin (thickness <1mm), Welding processing of small parts is more suitable for small precision laser welding.

2. When the power density on the focused spot of the laser is large enough, the metal is rapidly heated under the irradiation of the laser, and the surface temperature rises to the boiling point in a very short time, which can directly melt and vaporize the metal surface. When the metal is vaporized, the produced metal vapor leaves the molten pool at a certain speed. Therefore, if a deep and stable weld is to be formed, the power density on the laser spot needs to be controlled. If the power density is too large, the weld will burn through and cannot be fused; if the power density is too low, the weld will not be completely fused.

Therefore, under the needs of all walks of life today, laser welding has become the first choice for many precision machining welding. However, due to high-precision welding, the laser head is extremely demanding. It will be replaced after a period of time, just to prevent welding. The precision error of the process. The PURE-AIR laser smoke filter can deal with these smoke and smoke in the first time to protect the expensive laser head.
