Abstract:  
Keywords: Shot Peening, Electronic Intensity Sensor, Intensity Verification, Intensity Histograms Introduction Almen strips are often used for peening intensity determination and verification. For intensity verification, one must measure the pre-bow of the Almen strip, install the strip on the holder, peen the strip for a period of time, remove the strip from the holder and measure the arc height of the strip with a dedicated gage. For intensity determination, these steps must be repeated at least four different times to generate a saturation curve. Intensity determination and verification can account for 10% to 30% of machine usage.
