Abstract:  
A method and apparatus for controlling a shot peening operation includes the measurement of pressures at the nozzle which directs the shot onto the workpiece and just downstream of the point where the conveying medium (generally compressed air) is communicated into the transport hose. By comparing these pressure levels with the pressures set forth in a table for a given mass rate of flow of shot through the transport hose, the peening operator can control the velocity of the shot particles applied to the workpiece, thereby controlling peening intensity.
