A key distinction between Rockwell testers and the Brinell, Vickers and Knoop testers is that the latter three use optical technology, while Rockwell does not—which generally makes it less costly, makes testing quick and easy, and the surface finish of the specimen is not critical. 

In this article, I will explore the basic principles of phased array ultrasonic inspection and predominantly its applications within the aerospace sector.

The transition from ICE to electric powertrain requires a complete review of the approach to quality and process controls. Some existing checks for ICE find even more extensive applications for the EV sector.

This article provides a brief introduction to a dynamic micro-indention measurement technique which can be useful to characterize materials that are hard to analyze using the well-known Vickers and Knoop measurements described in ASTM E364.

After integrating ATOS technology into its FAIR procedure, the metrology department experienced increasing internal inspection demand.

One of the more frequent questions we receive is: I am tapping a ¼-20 UNC 2B internal thread with an “H13” tap, what gage do I need to inspect the threaded holes in my parts after tapping?

Quality materials are the route to quality products. For a product to be fit-for-purpose and meet legislative and commercial requirements it must check several boxes.

A digital validation of the design variation to reduce prototype builds or solve build issues while increasing innovation.

In-situ monitoring (ISM) has plenty of room for growth and maturation, and thus in June 2022, ASTM International and NASA sponsored an ISM workshop.

Advanced 3D digitalization technologies offer a solution with a modernized NDT alternative that saves time and money and unlocks access to more information in a single measurement session.
