It has been shown that current increases with increasing of pit radius and decreases with increase of its depth. The calculation method is proposed and forecasting assessments of maximum depth of corrosion damaging of welded joint components of dissimilar pipes have been done. This method is grounded on the basic electrochemical parameters of materials of welded joints that received by standard potentiometric technique and also on numeric-analytical procedure of determining of corrosion current density on the internal tube surface, which consider of the given welded joint as three-electrode electrochemical system.
