Laser welding machine, also known as laser welding machine, laser welding machine, is a laser material processing machine, which is divided into laser mold welding machine, automatic laser welding machine, laser spot welding machine, fiber transmission laser welding machine according to its working mode. Laser welding uses high-energy laser pulses to locally heat the material in a small area. The energy of the laser radiation diffuses into the interior of the material through heat conduction, and the material is melted to form a specific molten pool for welding purposes.
Is the laser welding machine harmful to the body during the welding operation? I believe this issue is of great concern to most people.
In fact, the laser of the green laser pointer welding machine is the light energy emitted by the excitation, which is a kind of high-intensity light. The laser light emitted by the laser source can generally be considered as no physical harm if it is not in contact or invisible; Laser welding machines can cause ionizing radiation and stimulated radiation during the welding process. This induced radiation has a great influence on the eyes and the body. Although the laser beam is very small, if you look at the spark generated by cutting for a long time, it is harmful to the eyes and has a tingling sensation. Therefore, in the case of long-term viewing of the light source, the operator must wear a radiation protective glasses.
Guangli Technology Laser Methane Sensor has been produced in small batches
Recently, after nearly 9 years of research, the Institute of Semiconductors of the Chinese Academy of Sciences and the Beijing Hangxing Joint Laboratory have successfully developed a new generation of semiconductor laser gas sensor domestic chips, and have already had large-scale mass production conditions, and have now been made into lasers.
Hangxing shares realized large-scale mass production of methane laser gas sensor chips, indicating that domestically replaced imported chips will be realized. In terms of the company, Hanwei Technology is the leader in the segmentation of gas sensors, and the photonics laser methane sensor has been produced in small batches.
According to the data, Hanwei Technology is a leading company in the domestic gas detection instrument industry. Since its establishment, Guangli Technology has been specialized in the development, production and sales of coal mine safety monitoring instruments and equipment, and large-scale equipment operation status safety monitoring equipment in the power industry.
