Green welding and environmental protection

2021-09-23

 The traditional electric welding process has low efficiency, high enterprise investment cost and serious pollution. Recently, the country has been strictly investigating environmental protection issues, so what are the hazards of the traditional welding industry?

 
1. Produce metal smoke and dust hazards
 
The welding rod will produce a lot of smoke and dust, including iron oxide, manganese oxide and other substances under the action of high temperature melting produced by the electric arc. Long-term inhalation can cause fibrous lesions of lung tissue, which is called welder's pneumoconiosis, and it is often accompanied by manganese poisoning, fluorosis and metal smoke fever, which can cause damage to the lungs.
 
2. Harm of toxic gas 
 
Under the action of the high temperature and strong ultraviolet rays generated by the welding arc, a large amount of toxic gases such as carbon monoxide and nitrogen oxides will be generated around the arc area, which will corrode and damage the lungs of the human body.
 
3. Harm of arc radiation
 
The arc light produced by welding mainly includes infrared, ultraviolet and visible light. Among them, ultraviolet rays are mainly harmful to the human body through photochemical action. It damages the eyes and bare skin, causing keratoconjunctivitis (electric ophthalmia) and skin biliary erythema.
 
4. Polluted water quality
 
The waste water discharged from the electroplating plant is extremely harmful to the natural environment. Not only pollutes the land, but also pollutes the water source. People who drink contaminated water will suffer from various physiological chronic diseases, and these physiological diseases will affect the next generation and even the next generation. The crops grown on contaminated land will also contain poisons, threatening the lives of more people.
 
Now the country has stepped up environmental inspections of corporate factories, not only for the supervision of industry safety regulations, but also for the responsibility of our living environment, and for the tens of thousands of people living on this land. While seeking profits, an enterprise should be responsible to its employees and think about making contributions to the society in order to enable the enterprise and society to have a sustainable future.
 
Provide solutions for mechanical metal wear-resistant and anti-corrosion, and mechanical remanufacturing industries. Plasma surfacing machines are used to replace traditional electric welding and electroplating processes. Plasma surfacing equipment uses alloy powder, plasma flow heating, and cladding a wear-resistant and anti-corrosion layer on the metal surface, making the product more wear-resistant and durable.
 
Duomu is widely used in mining equipment such as picks, central troughs, hydraulic props, valves, drill bits, drill pipes and other petrochemical equipment. The plasma surfacing machine can realize automatic operation and reduce the physical damage to the welder. The new powder process reduces corporate pollution emissions, making environmental protection nowhere to be found.
