The laser welding machine has been widely used in the metal processing market.
The laser welding machine is a common machine for laser material processing.
The main principle of welding is heating, melting and cooling.
In the process of laser welding, sparks often glitter, and their working principle is laser. Will these be harmful to human body?
Laser is the light emitted by atoms with good directivity, high brightness, good monochromaticity and good coherence.
Compared with ordinary light, the brightness of the laser is better, and more accurate, and the light color is single.
Generally, the laser cannot be touched or seen, so it can be considered as almost harmless.
However, it should be noted that the temperature of the laser beam is very high. Never point the laser at people.
Pay attention to ventilation during the operation of the laser welding machine.
Pay attention to the inhalation of dust and metal particles.
The shielding gas is generally inert gas, but do not inhale too much.
It is recommended to wear a dust mask during operation.
It is best to stay away from the welding position during the welding process.
Although the laser source radiation hazard of the laser welding machine is almost zero, the welding process will lead to two other kinds of radiation, ionizing radiation and stimulated radiation.
This induced radiation is not lack of short wave, and has a great impact on the eyes and body. It is best to stay away from the welding spot and don’t look directly at the light source.
If you work close to laser welding, you’d better wear respiratory protective equipment, radiation protective clothing and eye masks.
