A method for deep roll peening a workpiece includes deep roll peening a workpiece by moving the workpiece along a feed path through multiple groups of opposed rollers that are arranged in series. Each group of opposed rollers includes a rim that defines a workpiece engagement surface that exerts a deep roll peening force on the workpiece. A deep roll peening system includes multiple groups of opposed rollers. Each of the opposed rollers is rotatably mounted and has a rim that defines a workpiece engagement surface. The workpiece engagement surfaces are spaced apart from each other by a gap. The groups are arranged in series such that the gaps define a feed path for receiving a workpiece into serial contact with the workpiece engagement surfaces.
