Laser welding machine has been widely used in the metal processing market, laser welding machine is a common machine for laser material processing, the main principle of welding is heating and cooling after melting. In the process of laser welding operations, there are often sparkles, and the working principle is laser, will these be harmful to the human body? 

Laser is a kind of light with good directivity, high brightness, good monochromism and good coherence. Compared with ordinary light, laser brightness is better, more accurate, and the light color is relatively simple. Laser generally can not be reached, also can not see, can be considered almost no harm, but it should be noted that the laser beam temperature is very high, do not point the laser at the human body out of the light.

The 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 inert gas, but do not inhale too much, and 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 laser source radiation hazard of the laser welding machine is almost no, but the welding process will lead to two other kinds of radiation, ionizing radiation and stimulated radiation, the induced radiation this lack of short wave, and the eyes, the body is not small, it is best to stay away from the solder joint, do not look directly at the light source. If it is laser welding close work, it is best to wear respiratory protection, wear radiation protection clothing, with an eye mask.
