Sir dead Zone ke bare video banaiye sir🙏🙏🙏🙏🙏🙏 please

[@NDTQuality]

Ok,
Sure, I will

[@Sachinverma-ui7og]

Sir please make a video on how to draw dac using flat bottom hole, & how to use during inspection.

[@NDTQuality]

I have made video for plotting DAC using SDH block. You can watch video in channel UT playlist.
DAC using FBH is not generally used. Instead of it use DGS

[@sachinsahare6807]

normal probe 10 dia 4mhz dead zone kitna hai sir v1 block 5mm not seen

[@NDTQuality]

One can't say dead zone length by dia and frequency of probe, there are many other factors

[@jamshedalam6263]

Sir, what is Dead zone? Is Near zone and Dead zone same?

[@NDTQuality]

No,
Both are different.
Please refer this video: Dead zone in Ultrasonic testing ll Initial pulse in UT ll Near zone Vs Dead zone

tr probe 10 dia 4mhz dead zone

[@NDTQuality]

No dead zone on screen

[@technicalhub670]

Far zone formula

[@NDTQuality]

No formula for far zone.
We considering only beam spread in Far zone

[@sanjeevndt9592]

aws se scaning formula kya hai please ek video banaye sir🙏🙏🙏🙏 aap bahut Achcha samajhate hai. Thank you 🙏🙏🙏🙏🙏

[@NDTQuality]

Ok,
I will make video on AWS D1.1 UT scanning soon

[@imamhasan3555]

Sir intensity video banaye

[@sunitasoni996]

Sir dead zone front surface se kuch kuch niche tak hota h jo initial pulse me show hota h means initial pulse ka jo horizontal width hoga wohi dead zone hota h but sir agar hum probe ko job surface pr na rakhe to bhi initial pulse banta h tab to yeh surface pr bhi nhi h tabhi bhi initial pulse generate ho raha h sir plz solve this confusion.?

[@NDTQuality]

Dead zone is came due to probe and machine , not due to specimen.

[@sunitasoni996]

@@NDTQuality Thanks sir for your response
But sir can you tell me exact how much penetrate dead zone in surface?

[@NDTQuality]

@@sunitasoni996 Again I am telling you that dead zone is not function of part, don't correlate both.

[@sureshdungariya6878]

Dear zone is ringing time of crystal...when crystal vibrates and transmit sound energy but can not received energy...due to this creates dead zone and we called it initial pulse..it's not generate in specimen
