电焊工尘肺 工业生产中,电焊作业非常广泛,尤其在造船、车辆、机械;锅炉制造等行业,焊工占有很大比例。所谓电焊工尘肺,是由于电焊作业中长期吸入高浓度电焊粉尘而引起的。 电焊粉尘主要来自焊接烟尘。焊条是由焊芯和药皮组成,其中焊芯含有大量铁粉,还含有碳、锰、硅、铬、镍、 Welder pneumoconiosis industrial production, welding a wide range of operations, especially in shipbuilding, vehicles, machinery; boiler manufacturing and other industries, a large proportion of welders. The so-called electrician pneumoconiosis, is due to long-term welding operations in high concentrations of dust caused by inhalation. Welding dust mainly from welding fumes. Welding rod is composed of welding core and coating, which contains a lot of iron core welding powder, but also contains carbon, manganese, silicon, chromium, nickel,
