中文摘要：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。
英文摘要：The welding test of gray cast-iron was carried out using arc 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.
