The corrosion performance of austenitic stainless weld deposits with and without microfissures has been evaluated by cyclic polarisation testing in 3·5% sodium chloride solution at room temperature to define the electrochemical behaviour. The corrosion test results revealed that the presence of microfissures in the weld deposit significantly degrades corrosion resistance. Corrosion attack preferentially occurred at the tips of microfissures in fissure-containing samples and at the interpass boundaries for fissure-free samples.
