Sir, please tell me, what is id crack& od crack full name?

love it!! Thank you!

Excellent video. As an NDT enthusiast/man of destiny, I found this to be most helpful.

How to identify the lopand lof. Video pls

Why don't you see LOSF from the other side of the weld?

Okay

Nice video man, good refresher.

REALLY awesome video's! On a PA course right now; this definitely helped!

great video, unique explanation of flaws

Hope to see more

Thank you sir

Thanks. This helped me alot

Nice video sir.....

Thanx for the upload video

Great video, I’m hooked if you have more.

Really impressed on your video! I am also intrigued. Would love to have a conversation with you.

love this already shared to a few of my friends and lvl 3s i know would be great if you do more than 4 videos.

Great Presentation! Expect more On PLANAR/Volumetric Defects Presentation in the S-Scan mode

Wow Amazing!!! I seen many flaw signal explanation but your idea using aluminum foil is fantastic!! Kindly do more video for PAUT & UT

Its really frustrating you didnt show the S-Scan of the porosity.

Can I watch any more videos of this series anywhere? I’ve only seen 2 on your channel

Man I love this. All the models used to represent the different types of flaws. Nice!

Darn Jeff, ya beat me to it! I had the flashlight all ready to go :)

Any new one?

Hello Jef, what you using UT Set ? Please inform.

Hi, What probe are you using ? olympus or ge?

Thanks

The visual aids were great way to show and next time I try to explain the difference I will definitely utilize and tell them to watch your video. Love NDT after 20years still learning.

great explanations in both videos so far...I wish you were training me:-) Looking forward to more videos...different types of welds and immersion tank:-)

Good !!thank you!!!

Very good videos for learning

👍👍👍 excellent viedo!

Great explanation of volumetric flaws! Can't wait to see your next viedos and hope you don't mind me using your training aides in the future. I have some custom plotter cards I make for myself and some coworkers, PM me if you'd like one for your training viedo.

Great Video! Thank you.

Great video. Exactly what i was looking for. Cheers

Thanks so much its amazing explaining 🙌🙌🙌🙌🙏

Good Stuff Jeff, I will share with my young UT technicians.

Thanks! Interesting, clear, not complicating things. Please may you explain how differentiate between root flaws (lock of penetration, ID crack) and weld root geometry (excess penetration)? With one side access only is reliable? Looking forward for more episodes, Regards!

Jeff- Very nice video. I like the good live training material showing both video and signal at the same time. Interesting explanation of using side drill hole analogy of slag for the wrap around signal. Regular text book explains the trailing signals from a slag different faces that gives reflection. Overall nice video and looking forward to see future episodes.
