Resonant Inspection: The Resonant Acoustic Method uses a form of the method called Resonant Ultrasound Spectroscopy (RUS), also popularly known as Resonant Inspection (RI). Resonant Inspection can detect imperfections such as variances in overall shape, weight, cracks, and density of parts. It can also detect if any process has been missed, such as a machine or heat treating process.
PASI has many fully automated/semi-automated testing cells used for crack detection that can typically handle all sizes of PM, wrought, stamped, forged, and cast parts, along with manual systems for portability on odd jobs.
