UT on Backing Bar Welds

[@b.squared]

Just got into structural steel and I am using a Sonotest d20+ your videos are so helpful

[@bobwayzie]

Good video, been waiting for a straight forward, spell-it-out backing bar video.

Great job Paul and thanks for the shout out for the art.

Always informative, always enjoyable...

Doing alot of exactly what you've demonstrated, single bevel backing bar, but 25, 28 and 32mm, exactly what you said, to start with shaking my head and ruler (Aussie in Australia ) out every 5 minutes, but now I look for the signals as a guide

[@bladexxlll6615]

Would be good to see your tutorial/explanation on scanning partial penetration joint welds with UT conventional

[@hollowayndtengineeringinc.5201]

If I had a sample I would. The conclusion would likely be: don't do it, too much geo.

[@weldingclassroom7171]

Thanks. I am introducing my HS students to NDE and checking their own groove welds. I'm a novice but very thankful for your videos. I spent hours yesterday playing with our UT machine and some vee grooves with backing. On that root signal, how would a bit of unfused bevel edge look?

[@hollowayndtengineeringinc.5201]

Great question! On the near side, pretty easy. The first of the twin peaks signal will rocket up. But on the opposite side it's much more difficult.

[@hossammohsen1119]

Kindly can you explain this with using phased array

[@DanielRowe528]

How do you determine the difference between a gap in between the bar and test plate and an indication?

[@hollowayndtengineeringinc.5201]

You have to scan from both sides

thanks Paul!

[@turdburglar1612]

Does Canda require those big 🐌 wedges that AWS calls out?

[@hollowayndtengineeringinc.5201]

No
