低氢焊条在日本是50年代初开始生产的。从此对它的优越性,必要性的认识一直在逐年扩大,增长。其使用量已增长到占焊条总量的11％。低氢焊条焊接时产生的气体,烟尘对人体的影响、比其他类型焊条大。我们将其为害程度进行了调查归纳,这对改进焊条的研究是有益的。电弧焊接对身体的明显危害首先是触电及电弧光以及飞溅等、至于因焊接时发生的气 Low-hydrogen electrodes were produced in Japan in the early 1950s. Since then, its understanding of its superiority and necessity has been expanding and growing year by year. Its usage has increased to 11% of the total welding rods. The gas generated during the welding of low-hydrogen welding rods has a greater impact on the human body than other types of electrodes. We have investigated and investigated the extent of damage, which is beneficial for improving the research of electrodes. The obvious harm to the body caused by arc welding is firstly electric shock, arc light, splash, etc.
