I am a boy, 19 years old, engaged in laser welding work for half a year, listen to them all say radiation, I want to know how much harm to the body in the end?
Great harm, general work 1 days, rest for 2 days
Lasers do not produce electromagnetic radiation. Laser light is like a spotlight, but the light we use (light-emitting diode) and semiconductor laser is a principle.
Well, let me tell you something. The following are the main points:The laser source emits a general contact laser can not, can not see, that almost no harm, but do note that non professionals don't contact laser source, otherwise it is very dangerous, as long as it is because of the invisibility and the energy is too high. In addition, the laser also belongs to the electromagnetic wave, but the welding machine uses the laser wave length to be very big, therefore does not have the ultraviolet ray and so on short wave long wave light radiation harm.Welding process should pay attention to ventilation, pay attention to dust, metal particles inhalation, pay attention to the protection of gas, are generally inert gas, although this type of gas is not toxic, but do not inhale too much.The best welding process from the welding position, while the radiation laser source welder almost no harm, but the welding process will lead to the other two kinds of radiation, ionizing radiation and stimulated radiation, the radiation induced by this lack of short wave, but for the eyes, the body is not a small impact, preferably away from the spot, don't look more.To sum up, if you are working at close range, it is better to bring breathing protectors, wear radiation protection clothing, with goggles.
