The advantages of removing the potential threats of unwanted residual stresses and exploiting the beneficial residual stresses by thermal and mechanical treatments are already known in welding communities. Beside the fact that some of the recently developed surface treatments in other industrial disciplines have not been applied for welds yet, a shortcoming in general is that a quantitative integration of these advantages has not kept pace with the developments in the field of characterization of polycrystalline materials. In this paper the necessity of development of the concept residual stress engineering for increasing the fatigue strength of components and structures will be discussed. Here beside the controlled residual stress conditioning and characterization of the surface layers, the quantitative consideration of the favorable material states as design credit is elementary. As another element, structural health monitoring should be integrated into the concept to control the stability of the induced material states and their effective functionality.
