WIG welding: “Clean” process with underestimated health risk
It is deemed a “clean” welding process creating only little welding fumes and is therefore often underestimated: WIG welding. The process harbors health risks which should not be underestimated. Welders are exposed to nitrogen oxides, radioactivity and ozone in particular. … >> more
Fine dust: the invisible danger
The danger is in the unseen: Fine dust is a threat to people. Specifically, ultra-fine dust particles constitute a health threat. This finding is becoming more accepted in science and practice and can be applied directly to welding or rather … >> more
Manual arc welding: Chromium VI compounds and more besides in the welding fumes
Up to the formation of chromium VI compounds: In manual arc welding, the kind of hazardous substances in the welding fumes is very much determined by the metal of the core rod and its covering. Particularly hazardous are high-alloy rod … >> more
Factors for the amount of welding fumes
How much welding fumes created in any welding work depends on many factors: Not only the method and the materials used influence the amount of welding fumes. The welding fumes emissions, expressed in mg/s, are smaller than the smoke and … >> more
Welding fumes and their varying effects
Not all welding fumes are the same. Hazardous substances created by the welding process have different effects on the human body. There are substances which affect the lungs, poisonous substances and carcinogenic substances – and they all harbor their own … >> more
How welding fumes and pollutants are created
If welding fumes are formed, a whole chain of physical and chemical processes is behind them. The pollutants in the welding fumes are also formed by very different elements during the welding process. Welding fumes are created at the high … >> more
Air return system for chrome-nickel welding works: the welding fumes separation class matters
Air return system through the extraction devices during chrome-nickel-steel welding works? In Germany the answer is clearly yes! At least as long as the extraction and filtering devices have the appropriate welding fumes separation class. Whereas the dust class is … >> more
Health hazard from welding fumes
Contaminants from welding hold a high potential hazard to the health of welders. This is dependent on welding process and material. Welding fumes pose an enormous potential hazard. Official tests show that fume particles are typically smaller than 1 micron, … >> more
