heal.abstract	The paper aims at investigating the corrosion behaviour of shipbuilding high strength steel (AH36) welds and its effect on their mechanical properties. The corrosion behaviour was investigated in 3.5% NaCl solution employing both electrochemical andweight loss measurements under accelerated aging conditions. Metallographic observations and micro-hardness measurements were also performed on specimens taken from the parent metal, heat affected zone and weld metal. The electrochemical results indicate that the heat affected zone presents the highest susceptibility to corrosion, whereas the weld zone is the most resistant to corrosion of the three distinct zones. The mechanical behaviour of corrosion was investigated through experimental testing (three point bending and tensile tests) on both corroded and non corrodedwelded and nonwelded specimens.The obtained results clearly indicate a degradation of the mechanical properties of steel welds due to the corrosion. The depth of the corrosion pits was also evaluated using the Ultrasonic C-scan Method. © 2008 Taylor & Francis Group, London.	en
