Laser welding machine, also often called laser welding machine and laser welding machine, is a machine for laser material processing. According to its working mode, it can be divided into laser mold welding machine, automatic laser welding machine, laser spot welding machine, and optical fiber transmission laser welding machine. Machine and optical welding is to use high-energy laser pulses to locally heat materials in a small area. The energy of laser radiation diffuses to the inside of materials through heat conduction, and the materials are melted to form a specific molten pool to achieve the purpose of welding. Therefore, in the process of operation, in order to ensure the safety of the operator, the operator must be clear about the precautions for the use of the laser welding machine and its operating regulations. Precautions and operating rules for the use of laser welding machines 1. When purchasing a laser welding machine, the laser equipment manufacturer will include a machine instruction manual. Be sure to read the instruction manual carefully and run the laser welding machine in strict accordance with the operating procedures to ensure that the equipment and personal safety are safe. Safety.
2, Before starting the laser welding machine, first check whether all parts of the laser welding machine are working normally. After the operation, check the laser welding machine and the workplace to eliminate hidden dangers and ensure safety without accidents. 3. Direct irradiation or strong reflection of the laser beam will cause combustibles to burn and cause a fire. In addition, there are thousands to tens of thousands of volts of high voltage in the laser, which will be damaged by electric shock. Therefore only trained personnel are allowed to operate the laser welding machine.
4. When the laser welding machine is welding, its laser power density is very high, and the beam is very thin, which is easy to cause burns to human eyes and skin. Therefore, the eyes should be protected during laser welding operations. On-site operators must wear laser-specific protective glasses. 5. The laser beam of the laser welding machine directly irradiating the skin will cause burns to the skin. Due to the long-term influence of diffuse reflection, it will also cause skin aging, inflammation and skin cancer lesions of the operator. Therefore, the on-site operator should wear work clothes to reduce diffuse reflection Impact.
6. The circulating water in the laser welding machine must be kept clean, otherwise, it will affect the output of the laser. The user can determine the cycle of changing the cooling water according to the start-up time, water quality and other conditions. Generally speaking, the water change cycle is shorter in summer than in winter some. 7. The casing of the laser welding machine needs to be connected with a safety ground. During work, do not look directly at the laser beam with your eyes, and do not let your body (such as your hand) touch the laser beam to avoid injury. 8. Pay attention to keep the environment and laser welding machine clean, and check whether the laser rod and optical components are polluted frequently.
9. If you need to overhaul the laser welding machine, you must cut off the power, and make sure that the charge on the energy storage capacitor has been discharged before proceeding, so as to avoid electric shock accidents. If abnormal phenomena occur during operation, power off (press<emergency shutdown>and air switch) check. Many industries are using laser welding machines more and more frequently, and the application of laser welding machines has also greatly improved work efficiency. At the same time, due to the high laser intensity of laser welding machines, ionizing radiation and stimulated radiation are likely to It will cause serious harm to the operator, so the safety risk of a laser welding machine should not be underestimated. The operator must strictly abide by the laser welding machine use precautions and operating regulations to run the laser welding machine. Safety is no small matter, safety first , must be carefully considered.
