"World of NDE 4.0" published

Digital transformation of the inspection systems is inevitable. Pursuit of this opportunity amidst uncertainty makes a well-defined purpose and robust process essential. This book provides an overview of the purpose of NDE 4.0 (why?), underlying technologies (what?), and ways to overcome the challenges (how?) to successfully pursue the confluence of emerging digital technologies with the evolving physical world of inspection.

NDE 4.0 YouTube Channel

Welcome to the World of NDE 4.0 March 24th 2020 the YouTube Channel regarding NDE 4.0 was started. We hope you enjoy this introduction and all following videos.

DGZfP Application Award 2019

2019-05-27 the german society for non-destructive testing (DGZfP) awarded the core team (Dr. Werner Heinrich (Siemens), Dr. Karsten Kolk (Siemens), Dr. Hubert Mooshofer (Siemens), and Dr. Johannes Vrana (VRANA GmbH)) with the application price 2019.


What is Industry 5.0?

The term Industry 5.0 was coined during the last 6 years. However, what does it mean? Is Industry 5.0 the fifth industrial evolution? What is the difference between Industry 4.0 and 5.0? Is Industry 5.0 the true evolution? What could be the fifth industrial revolution?

Digital Twin 3D Visu

Looking at publications on the subject of Digital Twins, it seems that a DT is a fancy 3D Visualization - this is quite an unfortunate situation. Digital Twins are THE core of the cyber-physical loops and should be the core of digital transformation projects. In this video, I am presenting my view on digital twins and on the wide variety of digital twins and threads.

UT Sizing Method Limits

For quality assurance decisions and engineering analysis, the size of indications is one of the most crucial pieces of information. We tend to put a lot of confidence into the sizing methods we use in ultrasonic testing but each of those methods has its limitations. This leaves one big question - do we have an overlap between the various methods or is there a gap? This video compares the methods and their limitations.
