heal.abstract	The research presented in this paper aims at determining the corrosion behavior of shipbuilding high strength steel (AH36) welds in 3.5% NaCl solution. Metallographic observations and micro-hardness measurements were performed on specimens taken from the parent metal, heat affected zone and weld metal. Electrochemical potentiodynamic sweeps, Polarization Resistance and Tafel extrapolation methods were employed to determine the corrosion behavior of each of the above zones. The interpretation of the polarization diagrams, for the different parts of the weld, showed different susceptibility to corrosion; the heat affected zone exhibits the highest susceptibility to corrosion, while the weld zone presents the lowest corrosion rates. The above results are demonstrated and also supported by micro-hardness measurements and microstructural studies. © 2005 Taylor & Francis Group.	en
