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

[marcinstefaniak]

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.

[emmanuelcharles]

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

Just started watching your video very informative.

[rizwanshaikh]

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

[sathurappandeepak]

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

[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!

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

[peteryosilee]

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

[thalua]

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

[aquilesaguilar]

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