Good day sir, we have to make a PAUT procedure but the client concern is transverse crack. Can you tell me or make a video discussing the right approach to finding transverse crack

can you give me contact number

Excellent Explanation sir 👍

thanks for the knowledge you r offer

Thanks for such a nice video..very informative

Great video as always. Thanks Paul

Thanks Paul for the explanation. Can you explain that after sensitivity calibration when we go for the first point of TCG calibration we are reducing the gain initially. After tracing, once we add the point, all angles compensates to 80% but the visual dB on omni scan doesn't increase. Can you please explain. Thanks

<PH uses SWIPE attack> <dB DROP takes 50 damage> <CRITICAL HIT>

Thanks sir🙏

I started UT in the late 70's with a USM2 /USK 6 ,you soon pick up the trigonometry ratios to determine flaw location. What has changed is the lost art of echo dynamics. Which was much easier with an analogue set. Determining a root pattern from LORF or hydrogen flake from N.M.I.s in a heavy forging. Having been a PCN examiner it is possible to get a distinction whilst failing to recognise and correctly identify any of the flaws in the exam samples. Which should be a concern, similar to radiography without Rad interpretation. I obtained my PAUT /Tofd qualification 10 years ago (not recertified it) PAUT will definatley take over from manual UT as the price of it drops and it becomes standard on UT sets. I have to admit after years of manual UT I found PAUT / Tofd in practise very boring. Last week I took part in corrosion mapping an oil processing spooling an 8 hour shift felt like two weeks.

Love your videos mate! Just about to jump into PAUT, super excited! Would love a video on your preferences for encoders, wire vs wheel encoders etc, how to use different encoders, what’s most practical for real world non test plate jobs? You’re doing gods work mate, keep this gold mine of a channel going!

I'm not surprised your sizing was inaccurate. You should only use 6db drop method on reflectors larger than the beam (Inverse Laws). Using it on a through thickness reflector like this would over size by 2-3 times. Max amp would have been very accurate if applied correctly.

Thank you for the shout out x

I always teach my students the 10/8 V-path in my UT classes. Love the Carolinas connections in this video: Adam Daniels at Sonaspection, FlawTech, and Vermon NDT.

Absolutely excellent training. I’m not out in the field doing the UT two step anymore, but I really could have benefited from these videos back when I was out in the field, I would find SOMETHING and didn’t know how to interpret, and I would facetime a friend who is a jedi master of UT so he could watch my screen.

1st again!

thank you Paul for taking the time and effort to break things down...i appreciate your dedication.

Awesome videos man, I appreciate that you do these. It is good to have a practical refresher to look at if I need a reminder of how something works. Besides I see you write your reports in crayon like I do so we are on the same page 🤣

Would you be able to do a video on explaining Refracted L Waves using a DMA-DLA Probe for austenitic stainless steels? A quick concept on why they are needed and quick set ups with the angle sweeps.

i cant believe i'm geeking out over how cool this drone is

thank u so much, i appreciate the explanation

Like to see more videos on MUT as well

"When in doubt blame it on wave mode conversion" - As I've always told the new guys The near side signal can be very large in amplitude and appear on the full weld in some piping I've work with. Visual, Manual UT, MT, RT, see nothing just a slighty concave at the edge of the root bead and I've no idea why it's so large.

Same video for velocity calibrations, not always a requirement if the +/- is within code allowance.

You should mention Praveen Pilgam here lol

Shouldn't have watched this half way through my course.... Thanks Paul!

Great video as always. Thanks. xox

Does this logic work the same if the sensitivity reflector is a different size than the TCG reflectors?

So just wedge delay then TCG?

Thank you 🙏so difficult to make anderstand to customer or level 3 because of codes and normes mistake. Kévin Grivel, NDT specialist in France.

It was indeed a nice explanation. There are still many folks around word doesn't know the basics of different calibration. This will help them to understand better.

Thanks sr, very useful.

Thanks 🙏🏼

Thank you very much for your fantastic videos as always. Just wondering, do you have any plans to do anything about TOFD? , probably it's something missing on your channel. Peace, best of luck ;)

Ha! I’m 1st!

Please share about UT technique T joint welding with backing bar in AWS D1.1.

The learning curve of BEAM TOOL is very steep

Good afternoon from Western Australia; I've been religiously watching Paul's videos for many, many moons and I always find something that I didn't know that I didn't know about UT, so thank you Paul for all your efforts. I am considering buying sonatest wave, and have been searching for a "6 months or 1 year" type of reviews to see how this instrument performs in real life situations. After all, UT testing is a messy business so I am wondering how this arrangement works where couplant is present and will inevitably transfer onto the screen, sometimes in quantities. Does this arrangement creates a limitation as far as controlling the instrument? I would appreciate any feedback from users, Thank you, Chris

Which CAD program are you using to create your surface? I have Inventor and Fusion. I would like to try doing this if you have a link to a tutorial for creating a surface using UT data.

Interesting concept, as additive manufacturing is now a thing, I wonder if you could record a profile, print out of a metallic material and start the chain again by scanning the same 'print' getting the same signal response - just wondering if a metallic printed material would lend itself to scanning with useable results?

Never considered using PAUT data like this. Ive sent mesh surfaces from Creaform scans to recreate dents and metal loss on scaled models piping, cool mementos if nothing else. Have you tried recreating weld defects using 100% infill? Think it would be a unique way to develop scan plans or teach newer techs. Essentially simulated flaw plates at a major fraction of cost. Only doubt is how well sound would travel, think the layering from printing would cause issue.

I was looking up what QUPA PAUT meant. But you basically summed it up for me. I Understand that it’s an instrument to inspect welds. Now, since I’m a helper in welding, do you think I could take an inspection class and move past the welding part? To be an inspector?

Just got into structural steel and I am using a Sonotest d20+ your videos are so helpful

Please explain AWS CLASS X and CLASS R INDICATION level sizing

Some codes just seem to want to make your life hard on purpose :(

Hello, I think probe resolution verification is missed here.. .

I think there is an error in the drawing shown in the AWS D1.1 standard (Figure 8.13-Typical IIW Type Block). The depth for a 50 mm diameter hole is shown as 23 mm. The sound speed equivalent of 23 mm Plexiglas is 50 mm for steel. AWS D1.1 block prices are high due to the error.😆😆

This is really helpful, don't do a lot of AWS specific inspection here in New Zealand so will remember this when it crops up again

Wonderful Paul I really enjoy all your videos, the way you explain is pretty clear and useful 😀 congratulations 🎊 and thank you so much for all this material!!! Go Canada 🇨🇦 jojo nice T-shirt 👌

Thanks Holloway, last Few week ago I have told my client about the AWS setting that there is no DAC, because AWS uses the Ref SDH 1.5 V1 block
