Shot peening is a metalworking process which is used to improve fatigue life and increase resistance to stress corrosion of metal parts. The process involves a controlled high velocity stream of steel shot or glass beads impacting a surface, creating a compressive stress layer. The most common applications involve automotive and aircraft parts. Because there is no method for directly inspecting a part to determine the nature of the compressive layer formed by the shot peening, automated operations are desirable to insure consistency and minimize human variables.
