The structure of welded junction of 1Cr18Ni9Ti austenite stainless steel plate and 1Crl3 martensite stain- less steel plate welding by 1Cr18Ni9Ti electrode has been observed and analyzed by metallographic method; and the polarization curves and alternating current impedance curves were measured by immersion test of simulation seawater solution to contrast and analyze the corrosion resistance of weld seam and parent metals. Results showed that the structure of weld junction was typical columnar solidified structure; in welded junction
the martensite parent metal and weld seam region were easy to be corroded
while the austenite parent metal was not easy to be corroded.
