| 摘 要： | 介绍了焊接修复大型铸件件时，采用电弧冷焊工艺，严格控制焊接顺序，采用栽丝法等措施，减少焊接应力，防止产生裂纹和焊缝剥离的成功经验。同时也证明了大面积补焊的经济方法是采用塑性较好的异质焊缝焊条铺底镶边，其余部分用碳钢焊条焊完，该方法对大型铸铁焊接修复具有较好的指导作用。

| Abstract: | This paper introduces the successful experience of non-preheat repair welding procedure of large iron castings. In order to reduce welding stress and prevent from weld crack and weld peeling off, weld sequence must be strictly controlled and the planting bolt technique is adopted. More economical method of repair welding in big area is that the groove face is welded using high plasticity electrode, the filling bead and cover pass are welded using carbon steel electrode. The method has guiding function on repairing welding of iron castings. |
