Basics of Ultrasonic Testing and Sizing

[@c.p.madhusudhan3453]

A lucid explanation of the A Scan, beloved of UT Inspectors

[@laxmansureshmandalwar1499]

It’s very informative thank you

[@NDE40]

You are very welcome

[@marcinstefaniak3427]

awesome video! I really appreciate that you create that video, as a person who had break in doing UT for almost two years I think this is huge help to get back in to UT.

[@emmanuelcharles7987]

Thank you for the explanation and the effort with the graphics to explain the concept. Much appreciated

[@aquilesaguilar6497]

Just started watching your video very informative.

[@NDE40]

Thanks you

[@rizwanshaikh1280]

Excellent sir... please make video about sensitivity determination using DGS diagram.

I guess you will find what you are looking for in this video: kzbin.info/www/bejne/fp-zpK2bqNt-adk

Thanks sir

A great video.. Why can not we use audible frequency range of sound waves for industrial inspection?

[@NDE40]

The wavelength determines the minimal size of the objects you want to find - a wave with 10 kHz in steel (~6000m/s) allows you to find objects with ~0,5 METER (the lower limit would be something like 0,15m). With 2 MHz you can typically find indications of ~1 mm and larger.

Could you show us how to use piping calibration blocks for the inspection of diffrent pipe diamater??

[@peteryosilee6787]

Nice video, very informative. Would you plan to talk about new Sonar technology used in todays Fishfinders, such as LiveScope, ActiveTarget live sonar, etc.?

[@NDE40]

Up to the moment I focus on the application of ultrasonics for nondestructive material testing. Pretty soon I will do a video on TFM and SAFT - which are reconstructrion methods for ultrasonics. I guess they are used in new sonar technology. Perhaps I will do a bit of research.

@@NDE40 Great. Thanks!

Need echo pattern clarification

[@ananias-]

What’s your take on the idea that getting exposed to those X-rays will have health consequences? I am materials engineering graduate and looking forward to enroll in ntd program for certification. Any advice Thank you!

[@NDE40]

Being exposed the x or other rays has health consequences. This is why professionals who are exposed to radiation have to be monitored. In most countries the allowable dose is lower than natural radiation. This leads to the situation that the health consequences for such professionals are similar to those of everybody. So no worries. Just check the x-ray protection program of your country.

Nice! Do you plan to talk about other ultrasonic sizing methods such as TOFD, SAFT, etc.?

[@NDE40]

Definitely

[@aquilesaguilar6497]

Do you have a video on the best method to inspect ACSCC and limitations? PAUT vs UTSW

[@NDE40]

What is ACSCC?
