摘要
通过在铸件缺陷表面喷敷镍基合金过渡层 ,采用多元微合金化铸铁同质焊条大电流连续焊工艺 ,可获得无白口和裂纹的铸铁同质焊补区。为有性能要求的铸铁件的焊补 (接 )
By the procedure of spraying the Ni-matrix alloy transition layer on the surface of casting defect and using multi-alloying cast iron homogeneous electrode with high welding current and continuous welding technique, obtained the homogeneous welding zone in which there is no chill structure and crack. The process provided a new way for repair welding of iron casting required various properties.
