Abstract:  
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 . Subse quently , 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.
