Abstract:  
1999 Clemco Industries Corp. Reprinted with permission To be of any value, the shot peening process must be consistent and repeatable. To achieve those goals, your shot peening nozzle must deliver a uniform quantity of shot traveling at a consistent velocity as it strikes a given surface area. These two forces combine to produce the peening intensity, and peening intensity is what you measure when you read the arc of an Almen strip. Because most companies employ air-powered pressure blast shot peening systems, this article will concentrate on nozzles for pressure blasting.
