The sensitization degree of austenitic stainless steel welded joints was investigated by electrochemical methods of the double loop electrochemical potentiokinetic reactivation (DL EPR) in H(2)SO(4) + KSCN solution, and by the measurement of corrosion potential of the steel in the drop of the solution of HNO(3) + FeCl(3) + HCl. The welded joints were tested by X-ray radiographic method in order to check the presence of the weld defects. The grain sizes of the base metal and the welded joints were determined by optical microscopy. Good agreement between the results obtained by different electrochemical methods was obtained. The heat-affected zone (HAZ) of the austenitic stainless steel welded joints has shown a significant degree of sensitization. The double loop electrochemical potentiokinetic method gave quantitative evidence about the susceptibility of stainless steel to intergranular corrosion.
