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.

Chloromethane also called Methyl Chloride. It was once widely used as a refrigerant. It is a colorless extremely flammable gas with a mildly sweet odor. Due to concerns about its toxicity, it is no longer present in consumer products. Chloromethane was a widely used refrigerant, but its use has been discontinued due to its toxicity and flammability. Chloromethane was also once used for producing lead-based gasoline additives. The most important use of chloromethane today is as a chemical intermediate in the production of silicone polymers. Smaller quantities are used as a solvent in the manufacture of butyl rubber and in petroleum refining.
