电焊能引起电光性眼炎,还可以因高热和强光的刺激,引起眼晶状体混浊,或者患视网膜损伤等眼病。但危害最大的还是焊接时产生的烟尘。可引起慢性锰中毒、金属热,以及电焊工尘肺。 电焊烟尘主要由两部分组成,一是分散度很高的焊尘微粒,直径0.04—0.40微米,它是在电弧高温下产生的金属蒸汽冷却后凝集而成的;二是一氧化碳、二氧化碳、氮氧化物、臭氧和甲烷等多种有毒有害气体,它是由碳素燃烧和弧光的强烈电离作用而产生的。
Welding can cause electro-optic ophthalmia, but also due to high fever and strong light stimulation, causing ophthalmic lens opacity, or retinal damage and other eye diseases. But the most damaging is the smoke and dust generated during welding. May cause chronic manganese poisoning, metal heat, and welders pneumoconiosis. Welding fumes are mainly composed of two parts, one is the high degree of dispersion of dust particles, diameter 0.04-0.40 microns, which is generated in the arc of high temperature metal vapor condensation after cooling; the second is carbon monoxide, carbon dioxide, nitrogen oxides Materials, ozone and methane and other toxic and harmful gases, it is produced by the intense ionization of carbon burning and arc.
