防害治病电弧焊接在工业中应用非常广泛。为探讨电弧焊对工人眼睛的慢性损害,为加强电焊工人的劳动保护,特别是加强对眼睛的保护,我们于1993年6月至7月对365名电焊工的劳动条件、视力、眼睛翼状胬肉的患病情况进行了调查。被调查的365名电焊工分布在机械化工、轻工、船舶修造等行业的工厂中,均为专业电焊工,有时从事汽焊或钢材的切割。平均电焊时间为3—7小时/天。每年每人从事电焊工作220～290天左右。每人焊条平均用量5—20kg/天,焊条种类多为T 425、结222及T427、结507。
Prevention and treatment of arc welding in the industry is widely used. In order to explore the chronic damage to the eyes of workers caused by arc welding, in order to strengthen the labor protection for welders, especially the protection of the eyes, 365 working conditions of 365 welders, visual acuity, eye pterygium The prevalence of meat was investigated. The 365 welders surveyed are located in factories in the fields of mechanization, light industry, shipbuilding and other industries. They are professional welders, sometimes engaged in welding or cutting of steel products. The average welding time is 3-7 hours / day. Each person engaged in welding work 220 ~ 290 days or so. Each electrode average dosage of 5-20kg / day, the type of electrode is mostly T 425, knot 222 and T427, knot 507.
