Procedures for preventing corrosion of welded joints

Abstract

This paper describes the procedures for preventing corrosion of welded joints. Also, a theoretical overview of the forms of corrosion that are most prevalent in welded joints is presented. The concept of corrosion in welded joints is very pronounced in real conditions. Welded joints are inseparable joints that form an integral part of steel welded constructions. The internal energy increases during the fusion welding especially in the heat affected places around the welded joint, which become initiating spot of corrosion degradation. That is why it is of vital importance to focus on ways to increase the resistance of welded structures to the impact of corrosion.
