文摘The sensitization behavior of special structures such as weld seams reduces the resistance of materials to intergranular corrosion and intergranular stress corrosion cracking. How ever,the degree of sensitization in the seams could not be detected by the traditional electrochemical potentiokinetic reactivation（ EPR） measurement using the double loop method. Results based on non-effective tests bring risks to the application of these materials. In this study,the degree of sensitization in w eld seams are determined by using the scanning vibrating probe（ SVP）method.
