    Abstract: The peening is carried out by means of a device comprising an outer casing (5) of tubular shape which is placed so as to bear against one face of the tubular plate around one flush end of the tube to be peened. A tool comprising a shot-spraying nozzle is mounted so as to be able to move axially in the outer casing (5). The control device comprises at least one piezoelectric sensor (20) arranged in contact with the wall of the outer casing (5), and means (23, 24) for measuring the electric signal generated in the sensor (20). The shot-spraying nozzle is brought into the outer casing (5) in the region of the sensors (20) after each operation of peening a tube. The electric voltage of the signals produced by the sensors is measured. … …
