Flaw Characterization & Angle

Sometimes you need a little bit less, sometimes you need some more!
(Angle, that is)
Now, if you can pick out the 2 TV bits I picked those from, and you can hum the tunes, you win a prize!

UT2 here! Love you videos!
Would really enjoy seeing a video on probe angle selection and frequency selection for different scenarios in weld inspection!

[@Ratpackapunch]

I love your videos! Great practical information for all, Thanks Paul keep scrubbing!

[@gustiandrean4042]

Can't wait for your new content Mr. Holloway 👍👍👍

[@Ionbilly]

Great video as always Paul.

[@santiagocruz9060]

Great Paul, tanks for the very calre explanation

[@TheResiDogs520]

Great Info! Thanks for the video.

I work for a major aerospace company that works primarily with composites. Mostly carbon fiber. Would you ever consider covering composites? Love your content!!!

[@hollowayndtengineeringinc.5201]

You're the second person to mention it in a week. To be honest, I haven't really tried composites. My world is metals right now. But I'd give it a go if I had the chance

@@hollowayndtengineeringinc.5201 that'd be dope. Thanks for the reply!

Great!

I wish you was my teacher / tech / company lvl 3 lol

[@hollowayndtengineeringinc.5201]

That's nice of you to say, thanks! I am a Level 3 on retainer for a couple companies, but mostly here in Canada.

Great video! Can you also show how to UT flaw on aluminum welds? Thank you

[@russellpickering2444]

Hi Paul great video
However some of the draw backs of conventional UT with the 12mm + probe beam index can be over come by using close approach wedges and smaller diameter probes allowing steeper angles on smaller weld throats.
As a technician who started in the 1970's with USM 2 & USK 6 much more importance was given to echo dynamic pattern trace. This seems to be a lost artform due to the poor traces on the initial crop of UT sets in the 1990's

[@hollowayndtengineeringinc.5201]

I hear ya. I have some 1/4" transducers but the beam spread is so ugly the advantages of getting closer are a wash. It's all trig in the end though.

Hi i am from the UK any chance of doing something on part pen t- Butt seem to be coming across them more often best way of sizing the penetrant ie compression on the end of plate 6db drop or angle probe of plate?

[@AriasFelipe300]

Hello mister. Where can i get those plates with calibrated flaws ??

[@hollowayndtengineeringinc.5201]

You can get those from Flawtech in the US, Flawspec in Canada, or Sonaspection in the UK
