Is laser welding machine harmful to human body?
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 laser welding, sparks are often sparkling, and the working principle is laser. Are these harmful to the human body?
The laser is the light that is emitted by the atom 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 laser welding machine should pay attention to ventilation, pay attention to the inhalation of dust and metal particles. The protective gas is generally inert, 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 laser source radiation of the laser welding machine has almost no harm, but the welding process will cause two other kinds of radiation, ionizing radiation and stimulated radiation, this kind of induced radiation is not lacking. Short-wave, and the impact on the eyes, the body is not small, it is best to stay away from the solder joints, do not look directly at the light source. If you are working at close range with laser welding, it is best to wear respiratory protective gear, radiation protective clothing, and goggles. Howweld produce laser welding machine.
From the fundamental level, the laser cutting machine is generally not harmful to the human body.
Although the laser cutting machine is not inherently harmful to the human body, if it is used improperly during use, it will also cause certain damage to the human body:
1. Eye damage
When working with a laser cutting machine, workers often like to stare at the cutting head. If they stare at the cutting sparks for a long time, it will cause damage to the eyes and produce a tingling sensation. During the processing of the laser cutting machine, the emitted laser light can concentrate the energy and focus on the retina through the refractive medium of the eye to form an image, so that the energy density on the retina is significantly higher than the incident energy density on the cornea. The upper laser has good monochromaticity and small chromatic aberration in the fundus, so it will cause damage to the cornea or retina.
2. Skin damage
When the laser hits the skin, if its energy (power) is too large, it can cause skin damage. The damage can be repaired by the tissue, and the function will be reduced, but the overall functional structure will not be affected. If the skin is irradiated for a long time, it may cause burns and scars.
3. Respiratory system injury
When the laser is processing some special metal materials, the high temperature generated by the laser will combine with the gas and produce a large amount of dust, and most of these fumes contain a large amount of chemical components, and the dust will also be suspended in the air. Careless inhalation can cause damage to the human respiratory system. .
So how should we avoid the damage caused by fiber laser cutting machine?
1. Necessary protective equipment for the laser cutting machine should be prepared, and protective goggles should be worn to prevent laser damage to human eyes. Other people in the work area should not look directly at the laser during cutting.
2. Operators should pay attention to eat more carrots, bean sprouts, tomatoes, lean meat, animal liver and other foods rich in vitamin AC and protein, which can better protect the eyes.
3. Corresponding dust removal devices should be equipped, and try to operate in an unobstructed air environment, and wear masks.
4. When arranging the cutting site, the site and walls of the working environment should be painted dark to reduce radiation.
5. Do not touch the cut parts immediately after processing to avoid burns due to residual temperature.
6. Since the laser beam is an invisible beam, do not touch the light path during use to avoid damage to the body.
7. There are harmful elements (ZnSe) in the focusing lens of the laser cutting machine. Do not touch the lens frequently, and special treatment should be carried out after the lens is scrapped. Do not throw it away.
