3. Fatigue resistance of welded joints
3.1 Influencing factors
The fatigue strength of welded joints is influenced by a number of parameters related to the geometry and welding process, as well as the environment and treatments (coatings, finishing).
SCROLL TO TOP3.1.1 Influence of stress concentrations
The specific geometry of a welded joint, particularly the weld toe, is a particularly favorable location for the initiation of fatigue cracks. This is due to the local increase in stress, which depends mainly on the quality of the weld toe connection...
