Contrôle Non Destructif des Soudures par Ultrasons
L’inspection pour la qualité des soudures est une application typique du Contrôle Non Destructif (CND) par ultrason. Que ce soit pour valider les procédés de fabrication ou pour une inspection…
Flexible UT Inspection
Ultrasonic testing is one of the most effective ways to validate the integrity of aerospace composites. Introduction of automated ultrasonic testing for aerospace composites has benefited the non-destructive testing (NDT)…
Automated Ultrasonic Scanners: Impact of Axes Misalignment
Ultrasonic testing using immersion or squirter systems require appropriate metrological calibration and alignment in order to provide excellent system performances including repeatability and defect detectability. In addition, the required performances…
Automated Eddy Current Testing for Aero-engine Components
Advanced 3D Scanning Solution for Aero-engine Components Aero-engine disc components such as; bearing rings, fan and compressor discs are typically inspected at different stage of manufacturing from their pre-formed to…
Terahertz Imaging
Recently, electromagnetic radiation in the terahertz frequency range, best known as Terahertz radiation (hereafter abbreviated as THz), has emerged as one of the most promising measurement techniques for a variety…
Influence of Metal Microstructures
The internal structure of a component will influence how sound propagates through it. Most metal specimens are comprised of small single crystals called “grains”. Depending on the metal used and…
Grain Noise
If you are involved in the UT inspection of metals, and backscattered grain noise is making it difficult to reliably detect critical detects in some components, then this case study…
Time of Flight Diffraction Technique (TOFD)
Abstract The article begins with an introduction of TOFD technique principles. The main part reviews some recent literature wherein excellent results for TOFD were obtained, especially regarding speed. The author…
NDT – Phased Array Ultrasonic testing (PAUT)
LMATS’s PAUT experts have been involved in various research and development programs and have been pioneers in some of the techniques in Australia. The research and development program focused on…
A-Scans and C-Scans
The ultrasonic inspection of metals for internal defects is similar in many respects to searching for fish using an ultrasonic fish finder. In each case a sonic transducer sends out…
