Shear Wave Distance Calibration IIW Block

[@devonstephen3570]

Exactly the help I needed...I will share this video with my instructor and classmates!

[@JamesValentineBaja1000]

Mr. Clasen, Glad to see you on KZbin! I should come see you at CC soon!

[@jockellis]

Joe, thank you for putting up your videos. I passed both level I and II classes last December but have only gotten 8 hours of UTT. So anything that keeps my knowledge up is a big help. Hope I start a job next week with a company where I can get the remaining 842 hours.

[@floydarmstrong8212]

How is your nde career coming along? Hopefully swell!

[@jockellis]

@@floydarmstrong8212 at 72 I went to work full time for a machine shop that rebuilds industrial gearboxes doing mostly fluorescent MT but occasional visible with occasional visible dye penetrant inspections on welds and brass. It is a cushy job because we have overhead and boom cranes to do all the heavy lifting. Don’t get any UT though. I do have 132 hours of it though. I’m 75 now and have no plans for retirement. Thanks for asking.

[@JClasenCowleyNDT]

Thanks! We are trying to keep up in the world with nice newer equipment, let me know if there is anything that I can do to help you out. Joe

[@8inlinea]

this takes me back to fracture mechanics courses! thank you it's really a good presentation! I only wish we had beautiful instruments like that in our lab.. :s

[@JClasenCowleyNDT]

I'm glad you said it like that. I know that towards the end of the video there doesn't seem to be any "structure" and there is a specific reason for that. What I am performing here is just the calibration and then showing that it does work on the material, this video is not a specific defect location video. At least you liked the 1st part of the video! Thanks again! I appreciate the "constructive" criticism! Joe

[@williamhorvath3475]

I like your instructional videos. Its like going back to the nondestructive testing school at Chanute Air Force Base. I was in the US Navy at the time and that's where the aviation branch of the Navy went, along with the Marines. It would be neat to have these lectures on DVDs. Thanks for putting these videos together.

[@greasymuchacho]

I bet you do like them. YOU CHUMP!

[@ravishergill6476]

thanks a lot sir, your way of explanation & presentation is very helpful in learning even for us beginners

[@bluforcemotors]

Well explained, on the USM 35.....i ´m a german NDT Instructor and we USE the Karl Deutsch DE1090 for teaching.....our Blocks for Calibration looks similar and ar called K1 and K2 (of cause all in MM then)....keep up the cool vids will have an eye on it..... ;)

[@iir2d2ii]

Finally someone who can teach lol! I learned shear wave in school and all the steps to calibrating but it was so much and so little time that i barely could keep up.I also learned MT, PT, UT, RT.. but Im really interested in shear wave. Watching this video has helped me refresh my memory with how to cal for UT shear wave. Thank you please keep them coming..

[@JClasenCowleyNDT]

Thanks!, Appreciate it very much!

[@vlastimilpraus1520]

It is my job. I have this machine. Perfect video.

[@mittonitto1234]

Good teaching. I like your tutorial

[@JClasenCowleyNDT]

Will do, It will take me a week or so, but I can get one out there for you to use. Thanks Joe

[@JClasenCowleyNDT]

I am using a BNC connector on the UT unit and then a microdot connector on the TX.

[@mingli3183]

Hi Joe, thank you for sharing the good video to us. It is great and helpful. I have a question and look forward to your kind answer. In this video at the time 12:42, you rotated the transducer 90 degree so that the surface of transducer could not be fully covered, and the peak signals on the screen disappeared. Is it reqiured to fully cover the surface of transducer during measurement? I would like to measure the E modulus of gauge section in tensile samples. The width of gauge section is 6mm, but the diameter of transducer is 13mm. Is it possible to measure it? Or should I have to prepare the samples with width larger than the diameter of transducer? Thank you in advance!

[@DIMITRIOSPLATARAS]

EXCELLENT PRESENTATION. GREETINGS FROM GREECE

[@JClasenCowleyNDT]

This is something that we have gone over in class, so my students have this information. Sorry, I know that doesn't help you, but if your would like the info we were using a 70º wedge, shear wave, steel test block (steel weld as well), with a material velocity of 130,000 inches per second. Thanks

[@JClasenCowleyNDT]

Robotrob, You recieve signals at 1,5,9 because the block is built with a 1" radius and a 3" radius on either side, so once that is seen, you then point it either direction to see the signals at those locations.

[@JClasenCowleyNDT]

Joel, Did you find a weld that you are looking for? I have been doing some thinking and there are places that can make you welds. Either Flaw Tech or Sonaspection can do that for you.

[@JClasenCowleyNDT]

Sorry to hear that, why do you think it does, and what can be done to improve it?

[@aliali-nn2gp]

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

[@oprofessoredgard]

Thank you!

[@stephaniem2370]

Hi Joe! My name is Stephanie. These videos are awesome and have been a great help to me. I attended courses at GE Technology Center in Cincinnati, Ohio in July of 2011 to obtain my Level I & II certificate of training. However, I haven't done anything pertaining to my certs just yet. I have a very important interview coming up and would love to speak with you about NDT because your knowledge and precision is what I want to gain for myself. Thanks.

[@irfannayeem5735]

Can you please mention the reason why are you getting the signal 1,5,9 on DSC block? The waves are touching 1-inch first and then 4 radius of the block right?

[@Vinish89]

plz share the vedio for 6mm FBH calibration in ultrasonic testing.

[@jockellis]

Robotrob216, the sound wave hits the radius at one inch then rebounds back but where it hits the plastic it doesn't register because of the angle. But that is two inches. It reflects and hits the three inch radius and records at 5 inches. It bounces back and strikes the plastic at 8 inches and does not record but reflects back to the one inch radius and records it as 9 inches. So you have 1, 5, 9 inches.

[@Cowleyelearning]

+jockellis Correct!Please let me know if I can help you in any way

[@crackersphdinwumbology2831]

I do NDT/NDI in the USAF active duty. Kinda cool seeing how successful of a job this is on the outside Fuckin hate UT inspections though. Couplant is awful and freezes three months of the year

[@JClasenCowleyNDT]

Joel, I apologize that I don't have any welds like that. I wish I could help there. Joe

[@oluwabiyi30]

I got a quick question, let say your plate thickness is .625" or 5/8", using a 10" range screen. What will be my paremeter to watch for on my screen in order to eliminate irrelevant reflection on my screen?

[@nikiojoy6177]

hi, good day! I just discovered your channel because I am working on a research study about more efficient ways on infrastructure evaluation. Maybe you could tell me where to buy the transducers? Thank you so much!

[@souj1000]

Hi, I am Joel from Brazil and for me was must important your videos about U.T, then I would like know if you don't have any videos of the joint with back weld. Thank you.

[@Airman..]

what type of connector do yo have on your USM35, is it a BNC? i want to get it but it user manual is totally vague about OEM connectors and says that it has to be specified by customer prior ordering the macine thanks

[@user-charlieccchong]

Thankyou Sir

[@mangeram2731]

Very nice sir ji

[@sarojthapa3807]

It is helpful for me.

[@Cowleyelearning]

Thanks Saroj!

[@AmitSingh-jz5qm]

Thanks sir

[@ilhamnurhamidi6115]

thank you Sir for your video. Can you teach me how to do calibration of 90 degree transducer? I get stuck with this thing. It is my final project in my Campus. Thank you

[@souj1000]

Ok Joe thank you very much, but could you indicate me any site?

[@Badapple414]

Can you show angle calibration on a DSC block, please?

[@eunicef1]

So what was the indication at 10:00?!? It looked like LoRF.

[@dinero_arador]

How do you evaluate it signals?

[@amangeldysutenov3947]

Hello ! Can you send me more video about UT USM 35 or USM 85 Need study course calibration with angle probe 45 -60-70 degrees

[@satishdornal1]

Hi Joe, I see you have used a V1 block with curved notch and I can understand it's purpose. However, I've seen V1 blocks with vertical notch. can you explain the purpose of a vertical notch on V1 block?

[@joeclasen1977]

Satish,It really depends on what you talking about for the vertical notch, there is a vertical notch on the V1 block, it is just located on the bottom from where the transducer is being used.Let me knowTHanksJoe

[@satishdornal1]

+Joe Clasen the v1 blocks I see have a straight notch (in place of curved notch) on the top were you place the probe to measure probe index. I wanted to know what purpose it served.

[@Cowleyelearning]

Satish,Sorry for the delayed reply here, but I wanted to get back to you so I could get you an answer. The purpose of this is to give you a repeating signal every 4" instead of the signals at 5" and 9".Many apologies for being late!Joe

[@satishdornal1]

+Cowley Online thanks a lot joe :)

[@Badapple414]

Please do, thanks.

[@IndraRNugraha]

Why we check material must use grease?

[@Cowleyelearning]

It really depends on the temperature of the piping or equipment you are inspecting. Sometimes grease actually works better because of the heat of the equipment.As well it is a bit more viscous so you don't have to worry about it drying out as quick and will fill in the gaps of the material you are inspecting....

[@rinomelvin9273]

how do you choose range or calculate range

[@JClasenCowleyNDT]

The range really depends on the thickness of your material that you are inspecting. If you have a thicker material, then depending on your V Path, you will need a longer range to compensate for it.

[@markmitsui1]

no angle? no mode index? range for the weld? material velocity? all are just a guess..

[@dinero_arador]

Where is you yardstick? I do not understand what do you do...

[@kalpeshsingh2670]

can you calibrate angle probe without v1 or v2 block?

[@joeclasen1977]

You can calibrate with either block, it doesn't matter, the signals will just be in different locations is all.

[@sofianyusof1400]

Hi all, I am candidate to attend CSWIP QC Coordinator soon pray for me for pass examination tq.

[@dereklikos4423]

You're suppose to straight beam calibrate first

[@baljindersandhu5667]

How much

[@JClasenCowleyNDT]

Stephanie, Sounds great! I am available really at any time, all I need to do is get some information from you and we can get started with whatever questions you have. My email is [e-mail] and I would be glad to help you out however I can! Thanks Joe

[@PEDRO-lq9ph]

Is this physics class?

[@wildasurbakti5234]

Miss translet to speak indonesian

[@JClasenCowleyNDT]

Right off the top of my head I don't know of any, sorry!

[@renellharris3109]

before the 7min mark of the video your fine the rest fail . your cal'd up scanning the piece on 10in screen cant see nothing , you cant tell whats going on on the scope like you stated you didnt do no formulas no nothing you just look like you playing around to me

[@dereklikos4423]

This really isn't teaching anything, you should show people to how to calculate v path so you know specifically where to look on the screen, also how to calculate Legs so you know which section of the weld it is in. Nice machine though.

[@shaynemason7065]

He does in other videos.

[@renellharris3109]

not*

[@dinero_arador]

Why Russian NDT Engineer are consider worse than West Engineers?! We are know not less than you!
