Crevice Corrosion in a Subsea System — Aspect Before Analysis

Hot cracking at the fusion line of the connector side, in a welded joint between a forging and a pipe, in a macrographic sample.  The region of the heat affected zone of the connector presents a dendritic aspect suggesting that the forging reduction rate of the connector was not too high and did not broke the cast structure.
