The procedure of localised corrosion damaging assessment on internal surface of welded dissimilar pipes is developed. Method is based on numerical-analytic model of dissimilar welded joint as three-electrode electrochemical system with using of the fundamental electrochemical parameters of composing materials, which were received by standard potentiometric methods. The data on general characterisation and maximal depth of localised damaging on internal surface of pipes are presented and analysed with dependence of term exploitation and composition of operating environment.
