Le traitement est effectué à l'aide d'un ensemble de convertisseurs à ultrasons pourvus d'outils disposés sur l'axe de déplacement du produit, le positionnement relatif des outils étant déterminé par la forme du produit tandis que le nombre d'outils est déterminé par le nombre requis d'impulsions par unité de surface à une vitesse donnée. L'amplitude des oscillations ultrasonores et la force de compression sont définies en fonction du degré de déformation plastique de la surface du produit. Cette invention permet d'accroître la vitesse de traitement pour une qualité et une stabilité spécifiées de celui-ci et d'augmenter la résistance à la fatigue et à la corrosion du produit.
