One of the indispensable equipments in the welding field mainly uses the principle of laser radiation for welding, so there are always people who are worried about its safety during use. Laser is a kind of high intensity light emitted by excitation. The laser emitted by a general laser source can be considered harmless if it can't be touched or seen. However, ionizing radiation and stimulated radiation will be produced in the process of laser welding, which has great influence on eyes and body, so it is necessary to stay away from the welding site when welding.
Although the radiation of laser welding machine to human body is basically within the safe range, non-professionals should not touch the laser source. Laser is a kind of beam with high invisibility and energy, and it is very dangerous once it is touched. Especially the eyes are the most harmful, so you must wear a pair of radiation-proof glasses when looking at the light source for a long time.
In fact, no matter whether there is radiation effect or not, as long as we wear respiratory protective equipment, radiation protective clothing and eye mask, pay attention to ventilation, pay attention to the inhalation of dust and metal particles, and take protective measures, we can avoid injury. This shows that we are responsible for our own health and personal safety.
