Electrochemical Examination of Fused Joints Between Metals


Nine combinations of butt welded plates were studied in seawater for galvanic couple, dissimilar metal type behavior. The potential differences and corrosion currents were determined for the filler material, heat affected zone, and parent metal. In seven of the nine cases, the heat affected zone was found to be anodic to the parent metal. In only one case was there a prospect of cathodic protection from the parent metal to the weld.
