ABSTRACT The post weld treatment of cyclically loaded weld seams is known to increase fatigue lifetime considerably. The potential of these measures is particularly made accessible in high cycle fatigue (HCF) and infinite life at and below the endurance limit. The availability of a complete analytical algorithm is desirable in order to benefit from post weld treatment already in the design phase. The transferability problem can only be solved by taking into account all relevant influences of the material and the component. A proposition of this kind is made considering the individual phenomena according to the current standard of knowledge. Size, surface, plastification and mean stress effects are of particular interest in this context. The required local stresses are taken from numerical analyses e. g. based on the Finite Element Method (FEM).
