Basics of Focusing with Phased Array

[@aerialrescuesolutions3277]

Totally awesome. I'll be watching as many of your videos as I can. Great editing and sound quality too. Thank you kindly, Jim H.

Thanks Jim. This one has horrible lighting (I think my camera setting was wrong and I forgot to fix it in post) and I talked too much (as usual). They only get better! Cheers, P

[@aerialrescuesolutions3277]

I just watched it again, very well done. I didn't see any lighting issues, thank you, Jim.

Great demonstration, Paul! Maybe you could do some demonstration of the three major types of focusing? That would be a cool and useful demo to see in action.

Thank you very much for your informative videos.

Good video & thanks for taking the time to post.

Great videos! Could you film one about the compound S scan and if it really has benefits for common inspections? Thank you and keep on going!!!

[@hollowayndtengineeringinc.5201]

I totally would, but currently the Veo does not support compound. I think its a neat feature though. Have used it on the Omni.

Engineer Paul, in general, in Phased Array for V-bevel butt welds, should we work within the focused near field?

Thank u

If you we to use two16 element groups (1-16)&(17-32) from a 32 element prob (5L32-A11) would I be correct in assuming that each group would behave the same way a 16 element probe would. Smaller aperture, thus a smaller near field. Therefore less of a need to use focusing.

[@hollowayndtengineeringinc.5201]

You absolutely could, so yes much shorter NZ but also much poorer angular resolution. 16 doesn't look nearly as nice as 32.

[@jason3623]

👍 thanks for the quick response.

What is an E-Scan.

[@hollowayndtengineeringinc.5201]

Electronically rastered linear scan. Basically PAUT at one angle.
