A method for calibrating an electronic sensor for peening intensity. A range of desired intensity levels is chosen and that range may contain a single value or multiple values. The parameters for a blast stream are set that correspond to a particular intensity level. Test strips are peened in the blast stream and then the arcs of the peened strips are measured to determine the intensity level of the blast stream. Subsequently, a sensor is placed in the blast stream set at particular intensity levels and the signal generated at each intensity level is recorded. A roto-flap peening device can also be set at particular intensity levels and then a sensor is subjected to the roto-flap peening device set at those levels. A chart may be developed that correlates peening intensity to the signal of the sensor so the sensor may be used in place of Almen strips.
