G.V. Karpenko Physical-Mechanical Institute, NASU, Lviv, Ukraine

Abstract
The paper describes experimental-analytical methods of evaluation of local corrosion and local fracture of welded joints of the type of «anticorrosion cladding-casing steel». The constructed diagrams of electrochemical resistance and corrosion crack resistance of multilayer welded joints may be the basis for evaluation of the residual life of the considered joints.
Keywords: welded structures, casing steel, corrosion fatigue strength, heterogeneous systems, electrochemical proper¬ties, crevice corrosion, fatigue crack, metallic model, cyclic crack resistance, generalized diagrams, residual life
