International audience; High frequency hammer peening is a recent improvement method which is probably one of the most effective for treating welded assemblies. A number of experimental results relating to this process are presented in this article. These results lead to better understand the mechanisms of the process, to outline the influence of the operating parameters and to confirm the role played by the initial quality of the welds. In the long run, the aim of this study is to propose an industrially applicable approach for the fatigue design of welded assemblies treated by high frequency hammer peening. The numerical study carried out in parallel is presented in the IIW document: XIII-2395-11.

International audience; High frequency hammer peening is a recent improvement method which is probably one of the most effective for treating welded assemblies. The process applied in order to numerically estimate the effects of the treatment and to take into account the influence of its main parameters in order to optimize the treatment are presented in this article. These results were obtained in the scope of a study whose long-term aim is to propose an approach that can be industrially applicable for fatigue design of welded assemblies treated by high frequency hammer peening. The experimental study carried out in parallel is presented in the document IIW: XIII-2394-11.
