Zur Schwingungsrißkorrosion feuerverzinkter Schweißverbindungen unter Dauertauch- und Wechseltauchbeanspruchung

Corrosion fatigue of hot dip galvanized welded joints with permanent and alternate immersion Zink-coatings as corrosion protection of fatigue loaded welded constructions are of increasing importance. As corresponding design concepts in general are not available, corrosion fatigue tests with constant and variable amplitudes at filled welded joints are carried out under permanent immersion in artificial seawater or under alternate immersion in 5%-NaCl-solution including a lot of material, geometrical and fabricating parameters. The analysis of the results yields reliable informations with respect to the influence of hot dip galvanizing on the corrosion fatigue of welded joints.
