Journal ArticleDOI
Advanced technique for non-destructive testing of friction stir welding of metals
TL;DR: In this article, a new non-destructive testing (NDT) system focusing on micro size superficial defects in metallic joints is presented, which is composed by a new type of eddy currents probe, electronic devices for signal generation, conditioning and conversion, automated mechanized scanning and analysis software.
Journal ArticleDOI
Defect Characterization With Eddy Current Testing Using Nonlinear-Regression Feature Extraction and Artificial Neural Networks
TL;DR: A method to estimate dimensional parameters from eddy current testing data is reported, based on the modeling of the testing data by a template of additive Gaussian functions and nonlinear regressions to estimate their parameters.
Journal ArticleDOI
A differential planar eddy currents probe: Fundamentals, modeling and experimental evaluation
TL;DR: In this article, a planar probe with a differential operation was proposed to inspect imperfections along Friction Stir Welding joints, which was validated experimentally using an aluminum alloy block with standard defects produced using electro-discharge machining.
Journal ArticleDOI
Geometric optimization of a differential planar eddy currents probe for non-destructive testing
TL;DR: In this article, the influence of the geometrical parameters of an eddy currents planar probe intended for non-destructive testing is reported, and the results show that modifications of the studied parameters can substantially improve the probe performance targeting specific testing requirements.
Journal ArticleDOI
Contactless high-speed eddy current inspection of unidirectional carbon fiber reinforced polymer
TL;DR: In this article, the authors presented the development and results of a customized eddy current (EC) non-destructive testing (NDT) system for highly demanding online inspection conditions.
