摘　　要：为了解工程机械电焊工作场所存在的职业病危害因素及危害程度,采用定点及个体采样方法对某大型工种机械厂电焊车间进行采样分析,结果显示,该工作场所锰及其化合物、电焊烟尘时间加权平均浓度超出了国家职业接触限值,危害了工人身体健康,局部通风措施对控制电焊烟尘尤为重要。In order to learn about welding workplace occupational hazards in one engineering machinery company, it carries out the sample analysis by fixed point and individual sampling. The results show time weighted average concentrations of manganese and its compounds, and welding dust are beyond national occupational exposure limits, which are harmful to workers＇ health. The local ventilation measures are very important to control the welding dust.
