With the continuous development of laser welding machines, it is widely used in various industries, because it has very good welding efficiency, it has gradually replaced the traditional welding equipment. Although laser welding machines bring us high work efficiency, there are risks in processing work, and safe operation requires more attention. So what do you need to pay attention to?

 

1. It is necessary to inspect whether all parts of the welding machine are working properly.

 

Before the welding work, the laser (LASER) welding machine should be inspected for normal operation. After the operation, the welding machine and the working site should be inspected to eliminate hidden dangers and ensure safety and no accidents.

 

2. Avoid laser (LASER) radiation to cause fire

 

Laser (LASER) beam (LASER) direct or strong reflection can cause combustibles to burn, resulting in fire. In addition, thousands of tens of thousands of volts of high voltage electricity in the laser can be injured by electric injury. Laser welding technology has been widely used in the manufacture of foreign cars. According to statistics, in 2000, there were more than 100 laser tailoring production lines for cutting blanks worldwide, with an annual output of 70 million pieces of tailor welded blanks for car components, and continued to grow at a relatively high speed. Therefore only trained staff are allowed to operate the laser welder. The optical path system of the laser must be completely enclosed with metal to prevent the occurrence of direct irradiation. The laser welding workbench should also be shielded to prevent the radiation from being emitted.

 

3, should avoid laser damage (LASER) on the eyes

 

The laser (LASER) welding machine uses the power of the laser (refers to the amount of work done by the object in a unit of time) density (unit: g / cm3 or kg / m3) is large, the beam is very thin, it is easy for people Eyes and skin cause damage, so focus on eye protection during laser welding operations. Laser welding machine, also commonly 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 according to its working mode. Machine welding is the use of high-energy laser pulses to locally heat the material in a small area. The energy of the laser radiation diffuses into the material through heat conduction, and the material is melted to form a specific molten pool for welding purposes. Laser welding technology has been widely used in the manufacture of foreign cars. According to statistics, in 2000, there were more than 100 laser tailoring production lines for cutting blanks worldwide, with an annual output of 70 million pieces of tailor welded blanks for car components, and continued to grow at a relatively high speed. Field operators must wear laser-specific protective glasses.

 

4, should avoid laser (LASER) burns the skin

 

Direct exposure of the laser to the skin can cause burns to the skin. Long-term effects of diffuse reflexes can also cause skin aging, inflammation, and skin cancer in the operator. Field operators need to wear overalls to reduce the effects of diffuse reflections.
