Shear Wave Calcualtions 1

[@jerichosgv]

Thank you sir. Much needed explanation. I got it very easily with your teaching. Visually and mathematically. Thanks again !

[@edgarrobles6386]

Thanks so much I'm getting ready for an interview today and needed a to be refreshed. Great teacher. Thanks again!

[@compxci]

That's straight forward enough V distance is what we were all taught in basic Physics- 2dcos(x) =V distance and 1 leg is 1/2 (2d cos(x))= V/2..very good thank you- Skip is horizontal distance *2 which is 2*T*tan(x)

[@darianlubben5173]

Youre hot Joe, all the NDT talk makes me crazy!!!!! Just kidding, thanks for all the info. I have been out of the field for a while and your videos are the best refreshers ever!

[@bestunahmed3967]

Thank you so much for super useful information

[@bestunahmed3967]

Great teacher

[@JClasenCowleyNDT]

Depends on how you are trying to inspect it, are you inspecting the weld, or just the pipe?

[@arefahmadi6917]

How far we should scan from the toe of the weld to get 100% coverage? Is there any forform for that?

[@rajkumar1205]

Cool video

[@MrHyburn]

hello Sir, I live in Canada and commonly use the SI or metric system. Does this still work with metric or would I need to convert to in. for it to correctly calculate?

[@denswallmakins2511]

hello sir joe.. please let me know how do achieve the training online...

[@SweetWatch]

Appreciated

[@emesku]

Thank you for uploading

[@JClasenCowleyNDT]

@dummeswe What do you mean by IWI??

[@haikorudigr3818]

thank you for uploading this video. really helped a lot. I have my exam for NDT test tomorrow. there is one question I always worry about. I have used a 70° probe on a 0.472 inch sheet. was welded in V shape. my teacher told me why I had to do this this way but I have forgotten why is deepening on the sheet thickness which probe I use? I just remember he said something about inhomogeneities near the surface. otherwise I had to do two runs with 60 and 45° right? please answer I need to pass the apprenticeships professional discussion. sorry I'm German so my English might not be the best

[@JClasenCowleyNDT]

You would have to draw yourself a picture as to how you would want to inspect it. Or you could contact a company like Eclipse Scientific and they could set you up with a program called ES Beam Tool and that would allow you to put in all of the information that you have and create a scan plan from there. OR you could go to Olympus NDT with Phased Array and using phased array you could build a scan plan, of course you would have to be certified level II Phased Array

[@ildarmingazov2304]

Howdy! I grab this vid to learn some terms of ultrasonic method Thanks no end! Bye for now

[@bathulakirankumar9637]

Sir tell me, what are the probes which we are using for particular are in the qeld I mean 45° for bottom root 60° for cap in weld What is that actually

[@dummeswe]

Are you IWI?

[@compxci]

The IP, is it or was it an sine wave whose negative swing has been filtered out with a half wave rectifier?

[@JClasenCowleyNDT]

In this case, it may look like a sine wave, but as you can see we are just talking about basic UT here. Let me know if I can do anything for you!

[@compxci]

yes you can by the way, where can i enroll and get my NDT certification? I have BA in science already and three AS in electronics and engineering electronics. WHere is this you are teaching? I want to know, coz thejob I work now is in concrete testing and its not what I want to do. Please get back back to me at: [e-mail] my name is Jon, pleassure metting you. I am in the state of Pennsylvania by the way. Take care, hope to hear from you soon. -Jon

[@aliali-nn2gp]

can we used DAC curves plotted on steel calibration block for tasting aluminum welding by just to Chang the velocity

[@MrJFoster1984]

I wouldn't like to use the taste test for aluminium welding!

[@JClasenCowleyNDT]

gkndt123, Yes we do conduct UT training, depending on what you need we can customize classes to fit your needs. We also do Online NDT training as well. Let me know what you are interested in and I will try and help you out! Thanks Joe

[@BGIS2000]

S.A.I.T thank you.

[@compxci]

Are you cowley NDT?? I was interested in applying there for onsite classroom attendence, in March of this year, but never followed through..now you give me good reason to pursue it. Thank you

[@JClasenCowleyNDT]

Jon, I am, I have sent you an email, please feel free to reply back and we can get you started! Thanks Joe

[@rajeshtamang4408]

What if defect is in leg 1 ? Can it detect defect in leg one??

[@anthonyidoghor88]

Yes it can be detected

[@naqashmehmood2810]

how to calculate s wave velocity from p wave velocity

[@joeclasen1977]

Naqash, Just wanted to check in with you and see what you meant by the p wave? Maybe I'm not thinking of the correct term? Thanks Joe

[@The-Eastern-Coast]

the 70* angle of the probe, but in the material is it suppose to change? from probe to material? (snell's law) so my V-path should vary depending on the material it entered? In my opinion, the V-path in steel shouldn't be the same in aluminum when using the same probe, but I don't see how I would change my calculation depending the material?

[@joeclasen1977]

Floride, You are correct, the aluminum wave will be a different angle than the steel angle, typically you can buy a probe specifically for aluminum if that is what you are looking for. The difference is what degree the plexiglass wedge is cut to. Thanks Joe

[@balbirdogra973]

SO NICE

[@yasirarafath5580]

Thanks sir..

[@chanthasavann]

hello teacher

[@dummeswe]

@JClasenCowleyNDT Oh sorry international welding inspector

[@joeyrusso6988]

is it just me or is the math wrong?? vpath of that equation equals 3.15

[@Cowleyelearning]

Joey Russo Joey, I don't see what you are talking about here. I am coming with 5.84", where are you getting the 3.15?

[@jdown08]

Cowley Online He was using rad, not degrees

[@joeclasen1977]

+jdown08 Thanks for the update!
