Abstract
Un procédé et un appareil permettant daméliorer la résistance à la fatigue et à la fissuration par corrosion sous contrainte de surfaces irrégulières, comme celles dassemblages par soudage de composants, utilisant un système de positionnement, tel quune machine robotique ou CNC, pour positionner une tête doutil afin dinduire une compression le long et dans la surface dune pièce afin de suivre automatiquement les irrégularités de la surface. Le procédé et lappareil fonctionnent de manière à suivre une surface de commande virtuelle située sous la surface réelle de la pièce, ce qui permet à la surface topographique irrégulière dêtre traitée de façon uniforme avec une commande de processus en boucle fermée.
