very good video
Quick and informative - thanks!
Can this be used for non symmetrical objects?
Answer to "Can this be used for non symmetrical objects?": In principle yes, but it strongly depends on the individual geometry. It is possible if the eddy current is obstructed by a defect, and this can also work with non-symmetrical parts.
Hello thank you so much this i am sem operator i have worked 15 years
great video! studying for my cwi and this helps !!!
any hitonian here
let me know what app you use?
It is a the complete system "Krautkramer USLT 2000" which is no longer on the market.
such an excellet content! cheers from brazil

Imagine someone think something like that … is it through collection of several studies or is it just comming as an idea to come up with such stuff
The non-destructive chemical composition detection due to the type of emitted x-ray is freaking brilliant. Pieces of the puzzle become illuminated once you begin to construct the picture.

How to etch 3D printed 316 l sample ? I am etching with swab I can scratches I think those are of swab. Is it okay to deep sample in etchant
Answer to "How to etch 3D printed 316 l sample ? I am etching with swab I can scratches I think those are of swab. Is it okay to deep sample in etchant": It is generally better to prepare a good microsection and then immerse the entire microsection in the etchant, as shown in the video. Etching with a swab is also possible, but only soft and clean swabs should be used to avoid scratches.
Wow!
Why did u use the gell to that cylindrical thing, and then it worked? What was that cylindrical thing and how does it work?
To eliminate the gap between the transducer and test piece sir
Why we should mark distance with regular intervals?
Answer to "Why we should mark distance with regular intervals?": The marks at regular intervals are not absolutely necessary. Their main purpose in the video is to show the inhomogeneous plastic deformation of the sample. They also make it easier to determine the exact plastic properties. For professional or scientific purposes, the marks are very fine and precise, not as broad as in the video.

So, my UA-cam algorithm decided to show this video after my Non-destructive examination. 😌
Better late than never 😂
i rate that my drilla

I guess it's not necessary to put the drag-indicator at 0, only below the expected final position? At another video where many tests were executed the testerperson just give it a swing back for each test...
Answer to "I guess it's not necessary to put the drag-indicator at 0, only below the expected final position? At another video where many tests were executed the testerperson just give it a swing back for each test...": Correct!

Hi, could I use part of this video for my next video? It deals with the engineering of aircraft Panavia Tornado and I would give a short description of fatigue aspect. Thanks
Answer to "Hi, could I use part of this video for my next video? It deals with the engineering of aircraft Panavia Tornado and I would give a short description of fatigue aspect. Thanks": Sorry, that's not allowed; we've had bad experiences. Good luck with your videos!
ChatGPT brought me here ... thank you for the knowledge.
Very well explained
I just started doing this at my job. Still fairly new to it. How would i know the difference between a legit deep crack and one that is more of a surface defect? Not sure if you guys will understand what im trying to say lol
Answer to "I just started doing this at my job. Still fairly new to it. How would i know the difference between a legit deep crack and one that is more of a surface defect? Not sure if you guys will understand what im trying to say lol": This one of the problems of MPI, the depth of a crack cannot be measured reasonably.

Very nicely done! =Kudos to the voice-over actor, she pronounced everything correctly and gave the impression she was a true expert in the field. much to think about. The animation was excellent!!
Amazing conceptual explanation and demonstration
amazing. Crystal clear animation

Can make a video for gold atoms??
what a clean video. Engaging and straightforward. Thank you!
at 01:10, don’t forget that applying an alternating voltage is what creates an alternating current which will create an alternating magnetic field.
Answer to "at 01:10, don’t forget that applying an alternating voltage is what creates an alternating current which will create an alternating magnetic field.": Perfectly explained, thanks!
Hi, informative video, I have a question though: How to break a small sample out of a resin? if you have to perform hardness and you don't want the resin to effect the measurements, how shall I proceed to take out a sample from resin?
Answer to "How to break a small sample out of a resin? if you have to perform hardness and you don't want the resin to effect the measurements, how shall I proceed to take out a sample from resin?": You do not need to remove the sample from the resin. Select a suitable test force for the Vickers hardness test (e.g. 1 or 0.1 kp) and carry out the test. Only clamp the resin properly, it should not move horizontally or tilt. A slight elastic yielding has no consequences, as the Vickers test is force-controlled. Good luck!
Had this lab today except the resin capsule was a quarter of the size and was not fun to grind.
do not buy these cranks

The best ever tutorial video i had witnessed in past 10 years!! N
I've been a metallurgist for over 40 years - 2% Nital would have been better than 10% . Also why not refer to the steels as 1054, 1080 etc.
Answer to "I've been a metallurgist for over 40 years - 2% Nital would have been better than 10% . Also why not refer to the steels as 1054, 1080 etc.": Thank you! You are right about using 2% Nital. The etching time is longer, rinsing is easier, etc.. We used 10% Nital to speed up the etching time for the video. And we used the standardised European designations for the steels, simply because we live in Europe. Unfortunately, there are no international (ISO) steel designations yet.
Nice❤❤❤
Is this recommended for Marine Engineers
first time seeing this guy walking forward...
wow what a hitech machine, in my college the machine isn't automatic and its dial is also broken and we couldn't see anything through the microscope
