Description

Technical Field

[0001] The present invention relates to the technical field of welding fume treatment, and particularly to an operation method of an all-round welding fume absorption device. Background Art

[0002] In the modern industrial field, the welding of metal materials is one of the most basic structural part processing procedures. However, while the welding technology has developed rapidly, the harm caused by welding fumes to the environment and welders has not yet attracted sufficient attention. During the welding process, a large amount of spot welding fumes are generated, polluting the working environment. In the case of poor ventilation, the fume concentration usually exceeds several times the national standard, which can cause various occupational hazards such as welder's pneumoconiosis, manganese poisoning, respiratory tract inflammation, and neurasthenia. In order to ensure the physical health of operators in the welding environment, enterprises usually use welding fume purifiers to remove harmful substances in the welding fumes. The welding fume purifier filters the welding fumes using filter plates. To ensure the welding fume purification effect, after a period of time, the filter plates need to be replaced, increasing the production cost of the enterprise. Moreover, due to the height problem, the welding fume purifier can only be used when welding small workpieces, which is very inconvenient and seriously affects the work efficiency.

[0003] In view of the above problems, an operation method of an all-round welding fume absorption device is now developed. Summary of the Invention
