Propagation and Attenuation Characteristics of an Ultrasonic Beam in Dissimilar-Metal Welds

Propagation and Attenuation Characteristics of an Ultrasonic Beam in Dissimilar-Metal Welds

Ultrasonic inspection of welds joining dissimilar metals in nuclear power plants has proven to be a challenge, because the ultrasonic waves are subject to diffraction, distortion, scattering, and noise. These perturbations are due to their interactions with coarse-grained microstructures having anis...
