Abstract
A method and a system for evaluating stress corrosion cracking sensitivity of a welded component are provided. The method includes performing an in-situ tensile test on a welded component to be tested to obtain mechanical property parameters of each zone of the welded component to be tested; determining sizes and positions of notch specimens of the welded component to be tested by means of a finite element simulation method; processing specimens of the welded component to be tested; respectively performing a slow strain rate tensile test on the specimens of the welded component to be tested until the specimens are fractured in both an inert environment and a test environment, so as to obtain reductions of area of notch roots of the specimens of the welded component to be tested; and calculating stress corrosion cracking sensitivities of various zones of the welded component to be tested.
