Frequently Questions

How is laser processing technology carried out?

Laser processing technology is the technology of cutting, welding, surface treatment, punching and micro machining of materials (including metal and nonmetal) by the interaction of laser beam and material. Laser technology is a comprehensive technology which involves many subjects, such as light, machine, electricity, material and detection.

What should operators pay attention to when using laser products?

Answer: professional laser equipment belongs to the products, the operator must pay attention to the following points: 1. the use of laser equipment operating personnel must be trained, reached a certain level, and on the premise of security administrator with permission to mount guard operation; 2. laser equipment operator or close to the laser in use during the personnel should wear the appropriate laser protective goggles and protective clothing, wear protective glasses in the region, there must be a good indoor illumination, in order to ensure the smooth operation of the operator. In order to protect the operator, it must be equipped with machining, protection, screen and so on. There shall be laser diffusion protection in the processing room

Laser products may cause damage to the human body. How should we protect it during use?

The laser beam is a kind of high brightness, high power, high energy, strong laser irradiation on human skin caused by burns, if directly into the eye, or in a light (mirror like) surface reflection can also be caused by injury, will cause permanent damage to the eyes until blindness. Therefore, you should avoid putting any part of your body in the light path of the laser, especially paying attention to the protection of the eyes and skin so as not to cause harm. Different types of lasers do harm to humans differently. In laser processing, CO2 and YAG lasers are most commonly used. YAG laser can damage the retina of the eye

Why does fiber laser cutters not emit light?

If the laser cutting machine does not emit light, it will not be able to use the laser to cut the material. It will have a great impact on our production and processing. Therefore, we must check why the fiber laser cutting machine does not emit light, and reduce the failure of the fiber laser cutting machine, causing our economic losses. So, what causes fiber laser cutting machines not to emit light? 1, through the observation of fiber laser cutting machine current meter, check whether the current instruction, if there is no current instructions, fiber laser cutting machine of circuit should be checked; 2, check the fiber laser cutting machine water circulation
