| Abstract: | 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. |
