Hand welding operations, in industry, flexible, infrastructure and other sectors widely used. It not only covers a wide range of areas, but also occupies a large proportion of the toxic and hazardous jobs, and the production environment is easily contaminated with iron oxide, manganese oxide, fluoride, nitrogen oxide, carbon monoxide and ozone, exposing workers to dust and toxic substances Therefore, it is of great significance to eliminate the occupational poisoning of hand-held welders. Under the leadership of the party, under the leadership of the party, Qiqihar Railway Bureau takes class struggle as the key link, upholds the party’s basic line, relies on its own efforts to continuously improve the working conditions of electric welding. Through long-term practice, we have accumulated a great deal of experience and developed
