Creeping Waves Part 1 (Head Waves)

[@aerialrescuesolutions3277]

Awesome content. Since I saw your first video 4 months ago, I have been watching and re- watching. Thank you for your work, this information is very highly useful, your videos are well edited and concise. Really excellent work, Jim H.

Back in early 2004 I was using a creeper wave transducer to size cracks in our FCC unit. This was before PAUT was mainstream, in fact it was infant tech back then. We relied on high angle L-waves and tip diffraction for sizing. Good to see there is still value in creeper wave technique. If I remember correctly you can point that ducer directly at the side wall of your test block and see 3 signals pop up, indicative of a through wall crack.

How would we best inspect an inconel bonded layer to tungsten? The bonded layer is about 0.5-1.0mm. They are looking for cracking in the inconel layer. We were thinking of a plate wave or creeping wave just to look at that bonded (or unbonded) layer. Thanks

In Slovakia we call it Creeping wave :-)

Sir, pipe thickness 6.4 mm, dia 4".ut testing half skip catch one defect sir, but defect beam bath full beambath is coming, why is this happening, sir 70 degree probe use sir true angle 69 degree, but defect half skip and depth ok sir but beam bath only high full beam bath coming sir. Why sir. Please tell me sir

[@alessiobriganti5690]

Which software did you use for angle simulation?

[@hollowayndtengineeringinc.5201]

I mention it at 2:29. It's BeamTool from Eclipse Scientific

[@debasishroy638]

How do we measure the height of the crack using this technique?

Part Deux my friend!

I am doing a calibration and I noticed on the screen after the first distance there are two additional echos, then the second distance echo with two additional echos. what are these.

Will cover on next video. Hope to post on Jan 3rd.

You are a pioneer

[@bacelismael8687]

I have a silly question 😅 , what if I wanted to inspect pixiglass with a phased array probe mounted to a Wedge with a nominal refraction angle of (55°) in steel? , will this Wedge be able to produce Shear waves in phased array inspection? Or it'll be the same as in Conventional UT, as it'll be completely different from (55°) in steel?. Thank you always for your help, God bless you :)

[@hollowayndtengineeringinc.5201]

The glass that I use has a shear wave velocity very close to steel. So I don't need to make many adjustments. If you are in doubt about your sample, I would suggest having a reference target installed then compare to steel for echo position.

@@hollowayndtengineeringinc.5201 Thank you very much for your advice, really appreciate your kind support 🙏. Okay, I'll try two SDH's 👍

Hi. I cannot find part 2. Is it still available?

[@hollowayndtengineeringinc.5201]

Should be posted Monday AM Jan 3 2021

[@bacelismael8687]

So, dose this series include something regarding "Guided waves/long range UT" as well? Or is it another topic to cover in another videos?

[@hollowayndtengineeringinc.5201]

No guided waves in this series

[@bacelismael8687]

Ok, I'll wait for it then , no waves for me :|

[@phil107stein]

Are you asking me to like a video with an X3 inside? 🤯😅

[@hollowayndtengineeringinc.5201]

SVP! ;)

[@bacelismael8687]

There should be another version with Veo3 looool

[@hollowayndtengineeringinc.5201]

@@bacelismael8687 Plenty of Veo3 videos coming too! I have luxury of borrowing this X3 for another couple weeks so I want to make good use of it.

[@bacelismael8687]

@@hollowayndtengineeringinc.5201 Nice! , can't wait to see :). I get your point, Olympus's equipments aren't as affordable as other brands unfortunately :(. I wish to get my hands on some of them, one day.

[@drbaker2009]

I love my X3!
