Abstract:  
A method and apparatus for controlling a shot peening operation includes the measurement of pressures at two different points in a compound gas shot peening system. By comparing these pressure levels with the pressures set forth in a table for given mass rate of slow of shot, the peening operator can control the velocity of the shot particles applied to the workpiece, thereby controlling peening intensity.
