Article Preview

The present work studied the corrosion property around the fusion boundaries of a dissimilar steel welded joint in as-welded condition and after post-weld heat treatment (PWHT) in H2S containing solution with different times. An “in-situ-tracking” observation was proceeded for evaluating corrosive progress at the fusion boundary by using a scanning electron microscope (SEM). The results revealed that the fusion boundary was the worst region for corrosion resistance when comparing with other zones, and a broad boundary had a stronger resistance for “hydrogen induced disbonding” than a narrow one.
