Improved ultrasonic nondestructive testing of pressure vessels
Technical Report
·
OSTI ID:5861485
Progress in the development of synthetic aperture imaging techniques and a flaw detection technique for ultrasonic pulse-echo flaw evaluation is described. Synthetic aperture test results using narrow-beam probes show increased signal-to-noise ratios. Processing times for synthetic apertures constructed with wide-beam probes have been reduced. Results of deconvolution combined with synthetic aperture processing show enhanced resolution. Also included are images from scans over curved surfaces, initial results of a parameter study, a method for flaw detection based on time series models, and progress in the development of graphical displays.
