Corrosion
Corrosion – interactive engineering module focused on corrosion of welded joints. Learning format: Simulator · Interactive visualisation. Explains the principle, technical relationships and practical use.
Topic overview
Corrosion is not merely cosmetic rusting. Welded structures often combine a local chemical environment, different microstructures in weld metal and the HAZ, residual stresses, and geometric details such as crevices, washers or lap joints.
The images are used as consistent teaching visualisations. The text beneath each image explains the mechanism, typical risks and basic prevention. A real failure analysis must always confirm the material, environment, stress, surface condition and manufacturing history.
Uniform corrosion — Uniform material loss across the entire exposed surface. Typical of general atmospheric corrosion or environments without pronounced local passivation.
Galvanic corrosion — Occurs when two dissimilar metals are electrically connected in an electrolyte. The less noble metal acts as the anode and corrodes more rapidly.
