For the study of welding fume hazards,welding fume concentrations of J422 and J502 were determined experimentally in natural ventilation and local exhaust ventilation. Welding fume concentration distribution in space were analyzed,it's concentration was presented with the variation of time,the effects of electrode type of welding fume concentrations were summarized. The results have strong theoretical and practical significance of welding fume hazards assessment and treatment.
