A pipeline weld inspection is a common nondestructive testing (NDT) application in the oil and gas industry—and also challenging. Joining materials with different metallurgical properties, grain alignments, acoustic characteristics, cylindrical geometries, and other attributes can make flaws hard to ...
An algorithm adjusts and reconciles the TOF of these reflected waves to account for misalignment of the probe or part and surface geometry changes. It uses sound waves bouncing back from the front wall to conduct a scan from the direction opposite the probe array. The time-reversal PAUT process uses two steps: Comprehensive Coverage: A full ...
Phased array probes are divided by several characteristics, including: Probe Type. ...
In this study, an incident pulse signal of several harmonics (i.e., multiples of the fundamental frequency) was used as a source in the time domain reflectometry (TDR) probing technique. Reflected signals were captured by an oscilloscope and their characteristics were determined via eigendecomposition. ...
