Publikováno v: Journal of Applied Physics. 90:4829-4835

A noncontact laser–ultrasonic technique is described that allows determination of material properties of anisotropic platelike samples. The method requires access to only one side of the sample. Plane waves are synthesized by scanning the surface w

Inspection of Spot Welds Using an Ultrasonic Phased Array

Autor: D. Hopkins, F. Reverdy

Publikováno v: AIP Conference Proceedings.

Results are summarized for a series of experiments in which several hundred spot welds were inspected using high‐frequency phased‐array ultrasonic probes. Analysis of the signals in the Fourier domain allows identification of satisfactory, unders
