That “Unrestricted” in the bottom tells me this presentation was created on a Siemens system 😂

@NDE40 3 месяца назад

Close. In this case it tells you that the author worked for Siemens for many years.

@subhadeepbasu2936 3 года назад

Great video ! Does, sectoral scan and beam steering are the same ? In case of secoral scan, what combinations are used ? Is it aperture control along with focusing or aperture control alongwith angle control ? Thanks

@NDE40 3 года назад

Sectorial scans use beam steering. However, #1 sectorial scans are usually programmed to scan between two angles in certain increments and to show the result all the different angles are condensed into one picture (S-Scan). #2 beam steering is usually programmed angle by angle and evaluated using A-Scans. Usually, sectorial scans just use beam steering and with a fixed aperture. But with some more advanced instruments and with the right application .....

@premrp9987 2 года назад

why there is dead zone in tofd..??

@Taste_Budz 2 года назад

How do you calculate the NearZone for phase array probes?

@NDE40 2 года назад

Good topic for a future video - in essence you use the same formulas which you use for rectangular probes. However you have to calculate it for every angle and for every aperture individually.

@hehehaha755 2 года назад

Why its needed a linear scan? I mean whats the problem with exiting all the available crystals at a time and gathering the Data instead of linear scanning? Thank you.

@NDE40 2 года назад

If you fire all at one it is like having a very big probe. Very big probes are highly directional and highly focussed (naturally). Therefore you would NOT cover the area under the probe but only a small focal point. And tilted indicates would be very hard to detect at all.

@fa2417 3 года назад

Hi. Really nice video. Thank you. But the question is Do we really need the Phased array inspection in real inspection case (not for scince researchings) or it's just a playgame to spend some extra money, big enough money? Or we just enough with conventional inspection? Of course it depends of the task you need to resolve, but at 99% case of inspection

@NDE40 3 года назад

I would think at least in 50% of the inspection scenarios conventional UT is sufficient. A couple of scenarios where PAUT definitely makes sense: #1 automated UT electronic angle steering or sectorial or linear scans (both mainly due to the reduced number of probes); #2 manual UT: If it is not clear which probes you will need for the job. The situation is different with TFM - but more on this subject soon.

@fa2417 3 года назад

@@NDE40 I see. Thank you. Waiting for video about TFM

@dadasese69 2 года назад

This is well explained! Is this also how the 5g antenna works?

@NDE40 2 года назад

A 5G Antenna uses a 2D Phased Array of 64 (8x8) individual antennas and they are using the same beam stearing we are using with PAUT based on delay laws. So YES.
