Phased array inspection was conducted on a V-butt welded steel sample with multiple shallow flaws of varying depths. The inspection measurements were processed using Wiener filtering and Autoregressive Spectral Extrapolation (AS) to enhance the signa

Nondestructive Engineering: Applications.
The concepts of Fitness for Purpose (FFP), now popular in engineering, have placed greater demands on Non-Destructive Testing/Evaluation (NDT) to provide quantitative results. No NDT method seems better adapted to provide quantitative results than ul

The potential for crack initiation at a surface-breaking defect is strongly dependent on the radius of curvature p at the defect root: a small radius can lead to large stress concentrations which greatly increase the risk of crack initiation. In this

A method for estimating the root radius of curvature at the root of a surface breaking defect is investigated. The technique is based on the dependence of an ultrasonic diffraction pattern on the radius to wavelength ratio. The concept is applied to

Zr-Nb reactor pressure tubes are the primary pressure boundary of CANDU reactors. They are inspected for flaws by immersion ultrasonics, using a double-skip head and focussed transducers. These pressure tubes are 4.2 mm thick, and access is from one

Nondestructive Evaluation techniques such as eddy current or ultrasonics do not give a direct visual indication of the key characteristics of a flaw. Some form of signal interpretation is required in order to determine flaw type, size, and shape. One

Embrittlement of Zr−2.5%Nb pressure tubes from CANDU nuclear reactors has recently become a concern in the Canadian nuclear industry. While a full understanding of the mechanisms involved has not yet been achieved, it is known that hydrogen/deuteri
