Several years' measurements of the concentration of dusts and welding fumes, in one of metallurgic plants revealed the mean dust concentration of 3.6 mg/m2 at automatic welding workplace. At semiautomatic welding in CO2 screening the expected concentrations was 10 mg/m3, single measurements concentrations ranging from 0.6 mg/m3 to 140 mg/m3. A similar mean value was obtained from 6 Provincial Sanitary--Epidemiologic Stations. Analysis of data collected at 9 Provincial Sanitary--Epidemiologic Stations indicated that pneumoconiosis prevalence among welders operating semiautomatic equipment in CO2 screening was not higher than the prevalence among welders using screened electrodes. For dusts and welding fumes, the maximum allowable concentration value has been recommended.
在一家冶金厂对粉尘和焊接烟尘浓度进行了数年测量，结果显示自动焊接工作场所的平均粉尘浓度为3.6毫克/立方米。在二氧化碳保护半自动焊接中，预期浓度为10毫克/立方米，单次测量浓度范围为0.6毫克/立方米至140毫克/立方米。6个省级卫生防疫站也得出了类似的平均值。对9个省级卫生防疫站收集的数据进行分析表明，在二氧化碳保护下操作半自动设备的焊工中尘肺病患病率并不高于使用有保护涂层焊条的焊工。对于粉尘和焊接烟尘，已推荐了最大允许浓度值。
