In situ SEM observations revealed that compared with other zones the fusion boundary is the worst region for corrosion resistance due to the hydrogen induced disbonding, the corrosion resistance of the post--weld heat--treated joint is worse than that of the as--welded one and the fusion boundary with a broad scale has a stronger resistance for the hydrogen induced disbonding than the narrow one. These variations are related to the inhomogeneous microstructures, carbon diffusion, hydrogen--enrichment and stress concentration around the fusion boundary.
