Protection of welded joints against corrosion degradation
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2013 Welded joints form an integral part of steel constructions. Welded joints are undetachable joints, which are however subjects of corrosion processes. The internal energy increases during the fusion welding especially in the heat affected places around ...
