摘　　要：针对电焊所产生的焊接烟尘危害,对J422和J502两种焊条在自然通风和局部通风下进行了多工况条件的焊烟浓度进行了实验测定。分析了焊接烟尘浓度在空间上的分布特征,提出了其随时间的变化规律,总结了焊条类型对焊接烟尘浓度的影响。研究结果对焊接烟尘的危害评估与治理具有较强的理论和实践指导意义。For the study of welding fume hazards, welding fume concentrations of J422 and J502 were deter- mined 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.
