Vinod Viswanathan the instrument used in this video is a krautkramer using shear wave calibrated on an iiw block. Ising a 60 degree lucite wedge and piezoelectric cyrstal tansducer
X-ray is probably easier than this. Also looks like he's over doing it. Ut is great for some things but sheer wave is very tough to determine if you don't know part geometry. Just mag the whole weld with a yoke and call it good. And the machine is a USN 60
as im sure u know that magnetic particle with the red dust and wet mag only picks up surface and slightly subsurface indications and can only be used on CS. Like the man explained, UT can let you know the "exact" location and depth of the flaws. Plus, UT doesnt involve permits to do the job (depending on location) and slightly less liability insurance to be in business.
I don't trust any of this shit. I once saw an ultrasound technician do a UT on a weld, and said that it was the worst weld he had ever seen. He didn't know that the weld had also been X-rayed. The X-ray showed that there was nothing wrong with the weld. He was asked to leave the facility, because the plant didn't believe that he was competent. It concerns me about how often this stuff might be misinterpreted, and cause the welder to be asked to leave. There is no way to test these guys to insure their competence!
Hello Candyman Im agree "in part" about the way you think, I guess the problem is the education and training of NDT"s because some of them are express technician been developed just for some easier applications and basic geometries... Then when you change the parameters of test as thickness piece, material, geometry and other stuff they don't know how to perform well the test. For me the better way to develop a test; when piece configuration is hard, is to make a inspection plan in computer I mean a software simulation to be sure once you are in field you are doing the test well and what to expect. Other good thing to do when the NDT arrives is asking for his certification and better if this is issued for one NDT recognize institution as ASNT, ISO or some other NDT qualification standard. Im sure doing that things you will achieve a perfect and clear inspection.
X ray and ultrasonic testing is two totally different things brotha x ray can be good and UT can show up some rejects coming from a x ray and UT/NTD and CWI technician. 👍🏽
@@EDR1957coolkat This stuff is only as credible as the person who interprets the results. This is where the problem is. You get wildly different results from different techs. There is never supposed to be wildly different results between x-ray and ultrasound.
I'm new to UT inspection so forgive my ignorance but I really like that first leg/second leg set up do all UT detectors have that option?
Thank you very much...it is my new job. UT level 2. I am level2, PT, VT, LT, MT.
Best of luck in your new job
Sir pls explain by modsonic machinde
i have 2 questions, is this better then x-ray? how small defects can it found?
Why are you using a 60 degree transducer if it’s a one inch plate?
Thank you very much, sir! Can you teach us how to set
up and use the UT machine？
Video added on phased array
Sir your institution in india have or not ?
where is the dac?
Joselito Magat too thick for dac
Mayb basic to detect defect only
Dac is for ASME section V not AWS d 1.1
Phenomenal video !!! Really broke it down 💪🏻💪🏻💪🏻
sir echo is only 30% how you r conform this is defect
which procedure you are using,
how you scanning reference db or with scanning db
what is the name of this machine for using angle beam testing

not convinced about them being cracks :/ i need to see you wiggle and move the probe a bit more! ;)
Brendan Leonard no shit, and he is moving fast pushing that 6 inches per second too
@@michaelmonroe2002 that's typical for D1.1 But not asme
Sir can your have any link institute for tofd and paut course.
Video added yesterday on phased array
thank you
Thanks alot, Very useful, keep it up !
well down ,good leacture.
Another video added on phased array
Thank you very help full

As always, very good.
Do you have a email sir?
another video added on phased array
range calibrations using it method
Very good sir ,,👍
Very greafuly & Thanks
Excellent Job sir, stay blessed Ameen. Engineer Azhar Abbas khan
Sir please explain in Hindi
We are all requesting sir 🙏
بسیار زیبا ❤
So he is just giving the basics. I would find the flaws with a 60 or 70 and evaluate with a 1/4” 45 if I really wanted to find the nats ass.
you are not a certified inspector
ACFM kills all this...and faster...
