Laser welding machines have been widely used in the metal processing market. Laser welding machines are commonly used machines for laser material processing. The main principle of welding is to heat and melt and then cool and shape. In the process of pes laser welding, sparks are often sparkling, and the working principle is laser. Are these harmful to the human body?

Laser is a kind of light that is excited by atoms and has the characteristics of good directionality, high brightness, good monochromaticity and good coherence. Compared with ordinary light, laser light has better brightness, more precision, and single light color. The laser is generally inaccessible and invisible. It can be considered as almost harmless. However, it should be noted that the temperature of the laser beam is very high. Do not point the laser at the human body to emit light.

The handheld laser welding machine should pay attention to ventilation during the working process, pay attention to the inhalation of dust and metal particles. The protective gas is generally an inert gas, but do not inhale too much. It is recommended to wear a dust mask during the operation. It is best to stay away from the welding part during the welding process. 

Although the radiation hazard of the laser source of the laser welding machine is almost no, there are two other types of radiation during the welding process: ionizing radiation and stimulated radiation.This kind of induced radiation has no shortage of shortwaves, and it has a great impact on the eyes and body. 

If you are working at close range by laser welding, it is best to wear respiratory protective gear, radiation protective clothing, and goggles.You must use appropriate laser safety eyewear when this device is operating. The laser safety eyewear is selected according to the range of wavelengths emitted from this product. The end user must ensure that the laser safety eyewear being used protects against light emitted by the device over its entire range of wavelengths.
