I found your channel a few days ago and the way you present the information..I am a "shadetree" UT person who learned a little on his own with the GD books many years ago. I am interested in introducing my HS Welding students to UT and was wondering if you had any suggestions for any online resources for some preliminary training. Videos preferred but anything you suggest is worth me looking at. We have an old Epoch 3B and just bought a Dakota ultrasonics DFX7 that we will be ising to scan D1.1 test plates before bending. Have a great day! Gerald Austin
Best video with easy and superb explanation technically, Small doubt having two same frequency probes one with high damping and one with no damping, Is great improvement at near surface resolution with high damping probe accepted and practically noted the same.(we are making probe close to one frequency by damping - Broad band ) With no damping probe, near surface resolution very poor, but not bad as point of far surface resolution. What could be the effect to make this happen.
The ISO and resolution analogy is good to use but would there be a way to demonstrate with a similar method when using a C-scan system and how a good versus poor signal to noise ratio is encountered?

Great videos mate, keep them coming, I think one on mode conversion could be beneficial :)
Good Explanation! Thank you!
Would like to see a video on Bandwidth as well as most of the techs have difficulty in understanding it!
No problems Anup, I'll add it to my list!
Great explantion. Thankyou !

I would start with the Iowa State University website (www.nde-ed.org/)
Love this!!!!!

That's damping, a whole other video! :)
Ironically, this video took my ut understanding to help me better understand the tools on my dslr

Yes I think I will do that at some point
Hi Paul, a basic topic of ut grat explication, a question where buy the conector for lemoo 1?
I don't know actually... they were given to me
Good explanation.. +1
Help ful
great
