电焊时,会产生大量对人体有强烈刺激作用的短波紫外线。这种紫外线过多地照射人体,对人体有不良影响。除了电焊以外,气焊、电炉炼钢、水银石英灯、碳弧照明灯等,都可以产生较强的短波紫外线。 紫外线分为三类:长波紫外线,波长320～400毫微米,中波紫外线,波长275～320毫微米;短波
Welding, will produce a large number of human body has a strong stimulating effect of shortwave ultraviolet light. This ultraviolet light exposure to the human body, have a negative impact on the human body. In addition to welding, gas welding, electric steelmaking, mercury quartz lamps, carbon arc lamps, etc., can produce strong shortwave UV. UV is divided into three categories: long-wave UV, wavelength 320-400 nm, UVB, wavelength 275-320 nm; shortwave
