The laser welding machine has gained wide use in the metal processing industry.
As a predominant machine for laser material processing, laser welding machine is widely used.
The fundamental principle behind welding is the application of heat, followed by melting and cooling.
During the laser welding process, sparks generated by the laser may appear. Is it harmful to human health?
Laser light is emitted by atoms with high directional, brightness, monochromaticity and coherence properties.
Compared to normal light, laser light is brighter and more precise, with a single color.
As a general rule, laser light cannot be touched or seen, which makes it relatively safe.
However, it is important to note that the temperature of the laser beam is extremely high, so never point it at anyone.
Be sure to maintain adequate ventilation while operating the laser welding machine.
Take care to avoid inhaling dust and metal particles.
The shielding gas used is typically an inert gas, but avoid inhaling too much of it.
It is recommended to wear a dust mask during operation.
It is best to stay away from the welding area during the welding process.
Although the radiation from the laser source of the laser welding machine is almost zero, the welding process can cause two other forms of radiation: ionizing radiation and stimulated radiation.
This induced radiation does not lack shortwave radiation and can be harmful to the eyes and body. It is best to stay away from the welding point and not look directly at the light source.
If you work near laser welding, it is advisable to wear respiratory protection, radiation protective clothing and eye masks.
