Welders face a series of risks from dangerous substances that could mean they face time off work for illness or even early retirement. Different welding methods give rise to different amounts of fumes containing various concentrations of hazardous substances. Among the high-risk elements are hexavalent chromium Cr (VI), manganese, nickel and lead. The particle size (0.01-1μm) affects how toxic the fumes are. The smaller the particles, the more dangerous they become because they are easier to breathe in deeply in the lungs. The amount and type of welding fumes that are formed depend on the welding parameters and basic materials. It is therefore impossible to say that one method is always better or worse than another. The trend is that MIG, MAG and TIG welding are being used increasingly. These methods usually lead to an improved working environment.
