摘　　要：采用金相分析和电化学测试等方法，研究了采用3种不同成分体系的气体保护药芯焊丝焊接SGNS-A32钢板焊接接头的耐腐蚀性能。结果表明，3种焊接接头的力学性能均满足国际海事组织的要求；焊接接头焊缝与母材的高度差小于15μm，未见明显台阶。By means of the metallographic analysis and electrochemical testing, the corrosion resistance of SGNS-A32 steel welding joints with 3 different compositions gas shielded flux-cored wires is researched. The results show that the mechanical properties of 3 weld joints are good enough to meet the standards of International Maritime Organization （IMO）. The depth between the weld joint and base matal under the corrosion is less than 15 μm, and no obvious steps are observed.
