电焊作业在造船、建筑、国防等部门占有重要地位。该作业工人受多种职业有害因素的影响,可发生眼部疾病及神经、呼吸等系统的器质性病变。这些疾病主要是职业有害因素长期蓄积作用的结果,大多呈慢性经过,往往被人们忽视。因此,认识电焊工的职业危害,对于加强个人防护,保障职工身体健康有重要意义。电焊作业的种类很多。但是,我国目前仍以手工焊为主。因此,更容易受职业有害因素的影响。电焊时,电弧温度高达4000℃以上。一方面,产生大量紫外线;另方面,产生大量的含有二氧化
Welding operations in shipbuilding, construction, defense and other departments occupy an important position. The workers affected by a variety of occupational hazardous factors, ocular diseases and nervous, respiratory system may occur organic disease. These diseases are mainly the result of long-term accumulation of harmful occupational factors, most of which are chronic and often overlooked by people. Therefore, knowing the occupational hazards of welders is of great significance to strengthening personal protection and safeguarding the health of workers and staff. There are many types of welding jobs. However, our country is still based on manual welding. As a result, it is more susceptible to occupational hazards. Welding, the arc temperature up to 4000 ℃ above. On the one hand, a large amount of ultraviolet light is generated; on the other hand, a large amount of dioxygen is produced
