自制铜铁焊条和镍铜焊条的灰铸铁电弧冷焊研究

Research on Self-made Copper-iron and Nickel-copper Welding Electrode for Gray Cast-iron Cold Welding

采用自制铜铁焊条、镍铜焊条,运用电弧冷焊工艺对灰铸铁进行焊接试验,研究了其焊后接头的金相组织、硬度。结果表明,用所研制铜铁焊条、镍铜焊条进行铸铁补焊是可行的。

The welding test of gray cast-iron was carried out using are cold welding process and self-made copper-iron, the microstructure and hardness of welded joint were researched. The results show that it is feasible to cole weld gray cast-iron using the copper-iron and nickel-copper as welding electrode.
