Abstract:  
Peening Techniques Rust and fatigue never take a break, and our industry tries its best to get ahead of both miscreants! We blast clean parts to remove the last trace of scale, rust, or any other contaminant to present a clean surface for a downstream coating. We shot peen parts to generate residual compressive residual stress (CRS) that will combat fatigue and enhance the productive life of the component. With peening, we have adopted several other techniques in addition to shot peening using cast steel shot, cut wire shot, glass bead and ceramic shot. Such techniques include Rotary Flapper, Ultrasonic, Needle, Laser, Vibratory, Hammer, and Cavitation peening. Individual techniques continue to be adopted under specific circumstances and to achieve desired end goals.
