Sonats, a subsidiary of the Europe Technologies group, is the French inventor of the STRESSONIC ultrasonic peening process. Its equipment has been deployed for more than two decades on critical aerospace, nuclear and naval components — engine disks, thick welds, steam generator internals.
Kronos Engineering is an independent expert in special processes and operates on behalf of aerospace and nuclear principals. Our role on STRESSONIC technology: process expertise, AMS 2580 / AMS 2546 qualification, independent review of intensity / coverage / cycle parameters, and process-oriented operator training. This "process" expertise complements Sonats' "manufacturer" perspective.
