电焊作业广泛分布于各工业部门,电焊气溶胶对机体的危害与作业环境、通风状况、施焊类型、焊条种类及其配方成份,单位时间内消耗焊条量、基体金属、防护情况及个体差异等诸因素有关。电焊气溶胶的成份及其生物活性对机体有更直接的作用。 电焊气溶胶成份各家报道不一.Горбань等用奥氏体焊条,对中、高合金钢施以二氧化碳保护焊,所形成的气溶胶其固相成份中含锰30%、铬10%、镍6%。微粒具有高分散度,直径
Welding operations are widely distributed in various industrial sectors, welding aerosol hazards to the body and work environment, ventilation, welding type, electrode type and composition of ingredients, consumption of welding rod per unit time, the base metal, protective and individual differences Various factors. Welding aerosol composition and biological activity of the body has a more direct role. Welding aerosol composition varies reported .Горбань other austenitic electrode, the medium and high alloy steel carbon dioxide welding, the resulting aerosol solid content of 30% manganese, 10% chromium, nickel 6%. Particles with high dispersion, diameter
