Handheld laser welding machine is very popular in recent years, because it not only has all the original advantages of laser welding machine, but also has many advantages such as remote operation, flexibility and convenience. Compared with the traditional argon arc welding, the hand-held laser welding is more than 50% more efficient, smooth and even. It is easy to polish or does not need to polish after welding. Now it has become an expert in position C of the laser ring. However, while it is convenient to support hand-held welding equipment, we should put laser safety first! We should strictly follow the regulations when using.
1. Educate and train the staff who operate the handheld laser welding machine, so that the operator can understand the potential risks that may be presented when operating the hand-held laser welding equipment, and stop the appropriate laser safety exercise for the operator, as well as the emergency disposal methods when the risks are presented. Moreover, the management and application of lasers must be terminated by professional (professional) personnel, and personnel without training and education are not allowed to start and use the laser machine without authorization. When the machine was delivered to the customer, Vlasser strictly carried out standardized operation training, and pasted the operation requirements at a conspicuous place on the operation site. The machine must be operated normally, which requires turning on the host enabling switch, holding the gun head power switch, and pressing and holding the three switches of the light emitting button to prevent accidental injury. When the machine is delivered to the customer, the standardized operation training shall be strictly carried out, and the operation requirements shall be pasted at a conspicuous place on the operation site.
2. As we all know, the laser of the handheld laser welding machine is a kind of high intensity light, which is excited and emits light energy radiation. The laser emitted by the laser source can be considered as harmless when it cannot be contacted or seen; However, the laser welding machine will cause ionizing radiation and stimulated radiation in the welding process, and this induced radiation has a great impact on eyes and body. Although the laser beam is very small, and the operator generally likes to stare at the beam of the welding machine, if he watches the sparks generated by cutting for a long time, it is harmful to his eyes and will cause a tingling sensation. The retina is a very sensitive organ, so the operator must wear a radiation protection glasses when looking at the light source for a long time.
3. A large amount of ozone and oxynitride will be produced during laser welding; In particular, the concentration of ozone is far beyond the reference health standards, which has a great impact on human health. Therefore, good ventilation devices shall be provided at the work site to discharge harmful gases and metal dust. In addition, fire prevention equipment, such as sand box, fire extinguisher, fire hydrant, water bucket, etc. must be prepared. Flammables shall not be less than 5m from the welding site. If the specified distance cannot be met, asbestos board, asbestos cloth, etc. can be used to cover properly to prevent sparks from falling into flammable articles. The distance between explosive articles and welding place shall not be less than 10m.
4. Handheld laser welding machine belongs to high power laser equipment with safety level (IV). Therefore, when an unknown object enters the optical path, the automatic stop of laser power is a mandatory function. The safety of hand-held laser welding equipment is greatly improved. For example, the hand-held welding head with target recognition function, such as the hand-held welding head with intelligent real-time monitoring and timely fault warning, can reduce potential injuries.
