During the welding process, welding fumes will inevitably be generated, and these welding fumes will seriously endanger the health of operators and also pollute the atmospheric environment. The metal dust generated by welding is easily inhaled into the lungs, causing lesions. Under the action of welding arc and strong ultraviolet rays, an irritating poisonous gas will be produced. Long-term inhalation will cause occupational diseases such as bronchitis and emphysema. Similarly, these soot and dust are discharged without treatment, which is also a pollution to the atmosphere. very serious!
So, how to eliminate the harm caused by welding fumes? The editor shares four directions with you. These measures can basically solve the problem of welding fume control in most factories.
1. Update and improve welding processes and materials, so as to reduce welding fumes
The hazards caused by electric welding are mostly related to the composition of the electrode coating. By improving the electrode material and selecting clean, embroidered and oil-free welding materials, the generation and emission of harmful gases can be better reduced. In addition, welding should be made. The operation is transformed to mechanization and automation, and the application of welding robots can not only reduce the labor intensity of workers and improve productivity, but also protect the health of workers.
2. Welding fumes are collected directly at the welding point
Use the suction arm of the
Welding Fume Purifier to absorb the welding fume at the source, and then discharge it after purification by the welding fume purifier, which can better control the welding fume. soot.
3. Separate the welding area for centralized purification
If it is difficult to collect welding fume at the point where the welding fume is generated, the welding fume generated on the production line can be centrally treated by isolating the welding area. The more common situation is that the factory sets up a fixed closed welding room, or adopts mobile Type semi-closed fume exhaust hood, and then use the welding fume purifier to purify. In this way, the fume and dust generated by multiple welding stations can be collected and purified, and the emission of fume and dust can be better avoided to pollute other areas of the workshop.
4. Comprehensively collect workshop dust and carry out unified purification treatment
If it is a large workshop where large workpieces are welded with complex and changeable working conditions, it is more suitable to use this treatment method. The commonly used equipment in this method is a central welding fume purifier, such as large parts and special-shaped parts in the workshop, which need to be driven. The hoisted workpiece is welded and dedusted, so this processing method is more convenient and efficient.
