More videos!!!

Will be released soon ...

Talk about immersion testing in composite parts

[@NDE40]

Will come to that topic but first I need to do a couple more basic videos

Could you explain the terms “Index axis” and “Scan axis” in relation to the X, Y and Z axis for a robotic PAUT scanning system? Is this another way of converting a 3 way directional movement to a 2 way representation on a computer screen?

That is actually a quite a challenge. Index and Scan axis are pure surface coordinates. This is easy for flat components but it gets already quite complex if the component surface has a 3D shaped surface. And once you are using a robot: robotic coordinate systems are usually in 6 Dimensions: 3 dimensions for arm placement and 3 dimensions for probe orientation. Therefore you need a mapping from 6D to 2D - which is quite advanced linear algebra. A chapter of the Handbook of NDE 4.0 takes a look into the math of this issue: doi.org/10.1007/978-3-030-48200-8_5-1. But there are also some UT Instruments which can directly record 6D coordinates.

In the heat of the moment ;-) 18:00 Clearly not 1000s of probes but 1000s of channels 22:00 It is actually a system using air-coupled ultrasonics from Hilger NDT (www.hillger-ndt.de/)
