Portable Peening Capabilities in Maintenance, Repair, and Overhaul Environments using Ultrasonic Shot Peening

STRESSONIC® Ultrasonic Shot Peening provides an economical shot peening solution to FAA Part 145 Repair Stations including Maintenance, Repair, and Overhaul facilities. This technology brings shot peening repairs to the shop floor, which eliminates the need to ship components to approved Conventional Shot Peening vendors, reducing shipping cost and turnaround time for a repair, as well as reducing the likelihood of damaged components due to shipping. Through a Small Business Innovative Research project with the U.S. Army, Avion and SONATS-Empowering Technologies qualified the use of the Ruggedized StressVoyager® on repairs for flight Critical Safety Items. Testing revealed that Ultrasonic Shot Peening induces a compressive residual stress comparable to Conventional Shot Peening methods used by Original Equipment Manufacturers, eliminating the concern of creating any stress concentration gradient when using this technology for repairs.
