Based on experiments, the coating compositions of nickel ferro type castironelectrode have been worked out using regression method and computer - aided optimization.
If there aren't cast-ironelectrode, the cast-ironelectrode can be made by ordinary low carbon steel electrode, and repair the damaged stock with arc cold welding.
在没有铸铁焊条的情况下,采用普通低碳钢焊条制作铸铁焊条,用电弧冷焊技巧修复损坏的铸铁件。

The influence of Lanthanum, Cerium, Yttrium, Praseodymium and Neodymium on weld hot cracking susceptibility of the pure nickel electrode used for cold welding of castiron was studied.
