金属的气焊与气割在焊接生产中应用较为普遍。为使这方面工作多快好省地进行,使其在社会主义建设中更好地发挥作用,我们参照有关资料,并结合生产实践,围绕安全作业问题,简要地谈一点儿粗浅看法。以下谈六个方面的问题: 一、电石; 二、乙炔; 三、乙炔发生器及其使用时的注意事项; 四、氧气; 五、回火防止器; 六、安全作业常识及回火事故的应急处理。一、电石电石是在气焊、气割生产中取得高能燃料的最佳材料。它又是一级危险品。我
Metal welding and gas cutting welding production is more common in the production. In order to make this task faster and more economical and less costly, and make it play a better role in the socialist construction, we briefly referred to a few crude opinions based on the relevant information and in combination with the production practices and on the issue of safe operation. The following six aspects to talk about the problem: First, calcium carbide; Second, acetylene; Third, the acetylene generator and its precautions; Fourth, oxygen; Five, tempering prevention device; Sixth, safe operation knowledge and tempering accident Emergency treatment. First, calcium carbide calcium carbide is in the gas welding, gas cutting production to obtain the best material for high-energy fuel. It is also a dangerous goods. I
