Abstract:
The determionation of residual stress depth profiles in welded joints with mechanical surface treatments which are applied in welded components with regard to a better
fatigue performance is a great importance. The reason is that in principal considerations it could be shown, that the residual stress depth profile in the surrounding of
the weld toe resulting from mechanical post weld treatments can be correlated in combination with the local cold hardening directly with the local fatigue performance and
therefore with definite fatigue strength improvement of the welded joint.
