可锻铸铁的机械性能接近铸钢,是制造后桥壳、轮毂、制动鼓等的常用材料。然而,当用可锻铸铁制造的桥壳在使用时出现裂纹、磨损、螺孔损伤时,用电弧焊或气焊后,焊缝及熔合区常会产生白口组织。我公司用低碳焊条、电弧焊补工艺,不但能防止桥壳焊补后产生白口、裂纹,而且工艺简单、修复快、成本低,损伤的可锻铸 The mechanical properties of malleable iron close to the steel, is the manufacture of rear axle housing, wheels, brake drums and other materials commonly used. However, when the bridge shell made of malleable iron is cracked, worn and the screw hole is damaged during use, the white seam will often be formed in the weld and the fusion zone after arc welding or gas welding. My company uses low-carbon electrodes, arc welding make up technology, not only to prevent the bridge shell welded white back, crack, and the process is simple, fast repair, low cost, damage malleable
