In recent years, many industries are using laser welding machines more and more frequently. Laser welding is a very mature application of many laser technologies. In order to ensure the safety of operators, we need to master some safety operation specifications during the operation of laser welding machine.
1. Avoid laser welding machine damage to eyes
The power density of laser used in laser welding machine is very high, and the beam is very thin, which is easy to cause damage to human eyes and skin. Therefore, eyes should be protected during laser welding operation. Field operators must wear special protective glasses for laser.
2. Avoid burning the skin by laser. Direct irradiation of the skin by laser welding machine will burn the skin. The long-term influence of diffuse reflection will also lead to aging, inflammation and skin cancer of the operator’s skin. Field operators need to wear work clothes to reduce the impact of diffuse reflection.
3. Carefully read the operating instructions and operate the laser welding machine in strict accordance with the operating procedures to ensure the safety of equipment and personnel.
4. Check whether all parts of the laser welding machine work normally.
Before welding, check whether all parts of the laser welding machine work normally. After operation, check the welding machine and the work site to eliminate hidden dangers and ensure safety without accidents.
5. Avoid fire caused by laser welding machine irradiation.
Direct irradiation or strong reflection of the laser beam will cause combustion of combustibles, leading to fire. In addition, there are thousands to tens of thousands of volts of high voltage in the laser, which will be injured by electric shock. Therefore, only trained staff are allowed to operate the laser welding machine. The light path system of laser must be completely enclosed with metal to prevent direct irradiation. The workbench of laser welding should also be shielded to prevent radiation.
6. The circulating water in the laser welding machine must be kept clean, otherwise, it will affect the output size of the laser. You can determine the cycle of changing the cooling water according to the startup time, water quality and other conditions. Generally speaking, the water change cycle in summer is shorter than that in winter.
7. The shell of the laser welding machine needs to be connected with a safety ground. During work, do not face the laser beam with your eyes, and do not let your body (such as hands) contact the laser beam, so as to avoid injury.
8. Pay attention to keep the environment and laser welding machine clean, and always check whether the laser rod and optical elements are polluted.
9. If the laser welding machine needs to be overhauled, it must be powered off and the charge on the energy storage capacitor must be discharged to avoid electric shock. If there are abnormal phenomena during operation, it is necessary to cut off the power (press < emergency stop > and empty switch off) for inspection.
The arrival of laser welding machine has greatly improved your work efficiency. There are risks in processing work, and safe operation requires constant attention.
