CERT (CONSTANT EXTENSION RATE TESTING) AS A TEST METHOD FOR STRESS CORROSION CRACKING AT WELD JOINTS. 1: MECHANO-CHEMICAL TEST RESULTS

Investigations by means of CERT on the corrosive system structural steel/nitrate solution have been performed with special consideration of the influence of weld joints on stress corrosion cracking (SCC) susceptibility. Specimens with real weld joints and specimens with simulated weld joint structures (base material, course grain region, fine grain region) have been used. Results expressed as relative fracture energy show a significant influence of the heat affected zone of the simulated weld joints but not at the real weld joints. As expected, the SCC decreases in the sequence of the steels 15 Mo 3 - StE 355 - H II. All experiments exhibit increasing SCC resistance with increasing heat input. Part II of this work contains metallographic results and discussion of the applicability of CERT for weld joints.
