我用低碳钢焊条冷焊焊补铸件,在实践中摸索了一些经验,近半年来,在太原市的技术协作活动中,解决了本市和本公司的不少焊补关键,取得了较好的效果。具体焊接方法是将焊补处开成 V 形坡口,用低碳钢焊条先在坡口二侧堆焊三层,此时堆焊金属已由高碳钢过渡到低碳钢组织,然后在此基体上继续用低碳钢 I use low carbon steel welding cold welding parts, in the practice of exploring some experience in the past six months, in Taiyuan City, technical cooperation activities to solve the city and the company a lot of welding the key to obtain more Good results. The specific welding method is to open the welding fill V-groove, with low carbon steel electrodes in the groove on both sides of the first three layers of surfacing, then surfacing metal from high carbon steel transition to low carbon steel, and then at This base continues to use low-carbon steel
