Is fiber transmission laser welder harmful to people?
Is it YAG or carbon dioxide?!To do laser industry abroad, we must wear laser goggles. But in China, it is very rare, even in research institutes, laboratories, as well, very few people wear.I used to do laser marking, and found that after a day's work, vision dropped markedly, but it resumed in second days. But I recommend wearing laser goggles!
As long as the electronic products have radiation to the human body, the theory is harmful, short-term exposure without what too big impact on the body, but if often contact or harm to the human body, especially the impact of human fertility. Laser marking machine radiation will not be larger than the computer phone, although not harmful, but also need to avoid as much as possible! Don't always stare at the bright lights while you work. Be careful with your eyes!!
This is OK, that is, produce an instantaneous high temperature arc, no problem. My classmates often do experiments, they should be fine...
