| Abstract: | In this paper the effects of Ti, Nb, Co, Mo, Si and Y-Mg-Si-Fe alloy on the hot-crackingresistance of pure nickel electrode for welding cast iron were investigated. The test resultsshowedthat there was an optimum content of Ti, Nb, Co and Y-Mg in weld metal respective-ly. Thecomprehensive utilization of these elements can remarkably improve the hot-crackingresistance of pure nickel electrode for welding cast iron. The mechanical properties of its de-posited metal can match those of nodular cast iron with ferrite matrix (QT400-15). |
