42、加快上钢筋的下送速度，使其端部直接与渣池接触，这时，电弧熄灭而变电弧过程为电渣过程；待电渣过程产生的电阻热使上、下两钢筋的端部达到全截面均匀加热的时候，迅速将上钢筋向下顶压，挤出全部熔渣和液态金属，随即切断焊接电源，完成了焊接工作。c电渣压力焊的一些要求for more than 60 years of rural senior party member care funds; System of regulating the activities of grass-roots party organizations, and enhance the sense of belonging of
