Welding fume is an extremely fine-grained aerosol formed by oxidizing and condensing in the air due to the high temperature that melts the flux, the electrode core, and the material to be welded during the welding operation. The pneumoconiosis caused by long-term inhalation of high concentrations of welding dust is called the pneumoconiosis of welders. The occurrence of pneumoconiosis among welders is related to the type of work, length of service, and operating environment. Welders operate in open air or in spacious workshops with good ventilation, low dust concentration in workplaces, long onset of work, and low incidence. When operated under confined or poorly ventilated conditions, or when several welding torches are working at the same operation site, dust concentration is high in the operating environment, the onset of work is short, and the incidence rate is high. The welder’s incidence of pneumoconiosis is generally 10 to 20 years or more. In the high concentration of dust environment can be 3 to 5 years to disease. In short, the speed of onset is closely related to the welding environment, dust concentration, weather conditions, ventilation conditions, welding types, welding methods, operating time, and current intensity. Prevention of welders' pneumoconiosis should minimize sealed welding, use of automatic welding, the use of low-toxicity welding rods, welding helmets or air masks should be provided in the container. Welders should conduct regular occupational health examinations in accordance with relevant state regulations.
As the welder is a skilled workman with high technical content, this type of worker is often a laborer who has engaged in this industry for many years. If there is no regular occupational check-up, it may be very difficult for the welder to pneumoconiosis. However, there is no cure for pneumoconiosis. Protection of occupational diseases is important to them.
Welding fume protection (1) Ventilation measures Ventilation measures are effective measures to eliminate the hazards of welding dust and improve working conditions. Among them, local exhaust is the best in all types of ventilation measures, convenient and flexible, and cost-effective. Less effective measures are widely used in welding operations.
(2) Reforming welding processes and materials Rationally design the structure of the welding vessel so that the inside of the vessel is completely free of welds, and a new process of double-sided forming on one side is used as far as possible. This can reduce or avoid the opportunity of welding in the container, so that the operator to reduce the degree of harm; the use of non-toxic or less toxic welding material instead of a large welding material is also an effective measure to prevent occupational hazards. For example, various low-dust and low-toxicity welding rods; and if the current use of tungsten rods instead of neodymium tungsten rods can basically eliminate radioactive contamination, etc.; the application of industrial robots in the welding operation, will be able to fundamentally eliminate the welding of toxic gases Dust and other direct hazards to the welder.
Qingdao Su Shiqi dust removal equipment is specially designed for dust removal in the workshop, soot is collected at the source, zero-diffusion, highly purified, electrostatic smoke purifier for mobile welding dust removal equipment, mobile welding fume purifier, grinding dust removal table, moxibustion fume purifier, universal flexible Suction arm, articulated arm, activated carbon adsorption box, garage exhaust purification device, UV photocatalytic equipment, low-temperature plasma deodorization equipment, can inquire 18562630882 (WeChat synchronization) QQ
