IIW Type 2 Block and Pipe Inspection

[@burtonmaina]

As usual, excellent work. you contribution to the NDE/T industry is appreciated

[@JClasenCowleyNDT]

Rezque, I used just a general IIW type 2 block and the signals are coming off of the 2" and 4" reflectors on the front of the block. The transducer is a 60º standard shear wave tx. Let me know if that helps, if not, I will see if I can do something else to help you out. Joe

Really great videos! I hope you will upload some more soon because it's really interesting.

[@joshmceachern7596]

Awesome joe! Really like the videos! You should do a UT pencil probe lab calibration and thickness readings on a corroded pipe.

[@joeclasen1977]

Josh, Give me a week or so and i will get a video put together. Thanks Joe

[@joshmceachern7596]

Sounds good joe! I look forward to it.

[@joeclasen1977]

Josh, Just so I know, are you wanting to see a pencil probe with the diameter of the tx somewhere in the neighborhood of 1/4" or are you ok with a typical probe from a 38DL on corroded pipe?

[@jacobpayne4977]

can you make a video calibrating shear wave on a asme basic block type ? This would also be very helpful as all your videos are.

[@haroldishoy2113]

Joe, Since the USN 60 is so smart; would it be better to simply set the matl. velocity to shear wave for steel, and the probe angle to the correct value? (what angle 'ducer are you using?)

[@joeclasen1977]

+Harold Ishoy Thanks for the comment, one thing I have always liked to do is adjust the machine myself. I have never really gotten into the auto cal feature. I know it works really well, I have several friends that live by the auto cal feature. What do you think? In this case, All I use is a basic 5 Mhz .5" round transducer.

Hi Joe, Awesome Videos, well explained......although I am looking particularly for a video that can show me what particular defects looks like on the flaw detector. for eg....if we pick up porosity, what the peak or spike will look like....and so on for root undercut, what the spike looks like. and so on........also please can you help and tell me how to distinguish between false root echos and genuine defects....thanks Joe...hope to hear from you soon.

[@joeclasen1977]

Clinton, Let's talk and I can n walk you through what that would look like. I will be back in town next week and we can go over some things then if you like. [e-mail]

[@haroldishoy2113]

Shear wave method noted but if you are only inspecting 0.750" of material why do you have your range at 10 inches?

[@siddaram.talawar.8518]

He there. I just confused about sensors. When I calibrate machine with 12.5mm thickness v2 block I set nearly 38 db . After this on examination on even lesser thickness work piece put me to raise the db. Why this happened. Am I doing right or wrong? Can you please resolve it...!

[@ndi1414]

hi dear mr joe, we cant see the probe at standard understand from where the signal was gotten...rezeque

[@naturallife8053]

Hey Guy. Can you show me how to UT for pipe < 16 inch? What kind of probe we can use?

[@joshmceachern7596]

How is that video coming?

[@Cowleyelearning]

Josh, Sorry about that, It totally slipped my mind, I will get it up there next week, how about that?

[@ryanideishi]

Shouldn't you be scanning to a DAC curve on pipe that's under 24"?

[@joeclasen1977]

Ryan I True, I am only doing this for a class demonstration and then we hook up the DAC curve later.

[@ryanideishi]

I see, maybe a DAC video in the works?

[@joeclasen1977]

Ryan I I actually already have a DAC video out there, it is actually titled weird, it is Titled as a UT Lab Video. Thanks!

[@muhammadazam5150]

Nice demanstration.thanks.

[@yeziliz124]

Pretty basic, cool demonstration though. Thanks for the upload!

[@JClasenCowleyNDT]

Not a problem, thanks!

Very bad camera place
