We propose a method for the evaluation and perform prognostic assessments of the maximum depth of corrosion-induced defects in the components of combined circular welded joints of the pipes. The method is based on the use of fundamental electrochemical parameters of the materials of welded joints obtained by standard potentiometric methods and the developed numerical-analytic procedure of determination of the density of corrosion current on the inner surface of the pipe in which the analyzed combined welded joint is regarded as a three-electrode electrochemical system.
