Phased Array Ultrasonic Testing: Year-End Roundup
Phased array ultrasonic testing (PAUT) uses multiple ultrasonic elements and electronic time delays to generate and receive ultrasound, creating beams by constructive and destructive interference. As such, phased array offers significant technical advantages over conventional single-probe ultrasonic testing: the phased array beams can be steered, scanned, swept, and focused electronically. PAUT continues to be an […]
Cosmic Insight: What Are Muons?
. By David Mahon and Ernst Niederleithinger . No matter where in the world you’re reading this blog post, one thing is for sure… you are not alone! There’s no point in looking over your shoulder because your company cannot be seen by the naked eye. Let’s talk about muons. Muons are subatomic particles that […]
Applying NDT in Production
In the production stage, if there is a problem with the material used or the process implemented, it is best to have an immediate correction.
What Is Digital Image Correlation?
Digital image correlation (DIC) is a noncontact optical technique used for measuring full-field displacements and strains on the surface of objects undergoing deformation under loading conditions. Learn more in this episode of Chat NDT with ASNT.
Proper Use of Quantitative Quality Indicators (QQI) for Field Direction and Strength
The purpose of this blog post is to provide inspectors with a better understanding of the purpose, preparation, and use of quantitative quality indicators (QQIs) for determining the required magnetic field strength for magnetic particle inspection.
AI Will Shape the Future of NDE Data Analysis
Modern equipment used for nondestructive evaluation (NDE) can acquire more data faster than ever before. The benefits from these richer datasets are profound.

Meet ASNT’s 2023 Faces of NDT
ASNT is pleased to introduce the 2023 “Faces of NDT”, who will represent ASNT and NDT to the world.
Reducing False Calls When Scanning for Internal Corrosion Using the Echo to Echo Technique with Compression Ultrasonic Waves
Since most false calls are attributed to laminations and inclusions, this article looks at ways of differentiating laminations and inclusions from internal corrosion.
Reduce Train Derailments, Invest in Personnel
Nondestructive detection and characterization play a key role in monitoring the health of the North American railroad network, and ASNT has always played a role in disseminating emerging research on NDT of railroads.
NDT Method Overview: Learn the Basics of Acoustic Emission Analysis for Field Testing
Acoustic emission is a sudden, transient release of energy that takes place due to material deformation, structural failure, or something similar. Learn the basics of acoustic emission testing in this blog post by Stanley F. Botten.
