It can be very useful to increase the TCG gain instead of the global gain because you may avoid getting noise signals.

hello sir good day i !! sir i have been watching your all videos and learning something new in every look. and now i would like to request you to make a video about the linear beam setup and calibration calibration. i hope you will reply in my comment.

fun of fun thanks for ur comment.surely I will make a Calibration setup video for linear.

How much db we need to detect discontinuity ?

Hi Rakesh how are you? Hope you're doing great. Question, dont I need to put the gate on the echo location or the angle cusor on S scan before I click add?

Hi amada , h w r u ? Hope u fine ....if u r going for manual TCG u have to keep on one angle ( middle angle is better),& for the gate , u r question is right , however we can easily find out depth with A Scan display. For the doubt cases u can choose gate , Thank you amada . For ur valuable question

If TCG done not properly what will happen

ur basement( TCG )is not do properly means all parameters went wrong , mainly sizing.

Sir what you have provide a video of TCG on curve Notch block

Ved Prakash verma sir, currently I’m not working , when I start the job again I will make another video for that . FYI, Calibration block - curved notch block( using auto tcg)- in all laws Then 1 st point -0 add point 2 Nd point , Bottom notch 3 rd point , top notch

Hello 👋 Good video But i have one question....on what basis we decide that this is our scanning db ?

Rv Dheda reference db is based on TCG calibration. It’s means that every angle should be reached 80% amplitude . If u go through TCG means u can find out that one .and also after the completion of Tcg, u have to do daily Calin &out as per the daily job . According to that u can adjust the db ,

Did Code is allowing for Manual TCG ?

Calibration for reference sensitivity was made using the known calibration reflectors described in ASME Section V Article 4 and a time corrected gain (TCG) applied. For example- specimen pipe, cal reference Bottom &Top notch. So there is limitations for that. In the mean time we need to use . Otherwise auto TCG draw with standard block( Navship or IOW etc), then go for the Calin.

But ASME Section V. All mentioned all the Angle have equal response has to produced. As you known most of time we analysing the indications on amplitude reflection. If we will apply manual gain then Lower angle show more than 80% that time how we can Used to manual TCG gain for interpretation of indications ??

That’s y everyday before the work we need to do Calin & after the job need do cal out. If while doing calout time , any variation more than tolerance level means- re calibration ( a2 z)mandatory

Ur questions is right only . But some case we need to follow manual TCG, as I above mentioned. About sizing , u should prefer high aperture . So near field will increase then ur sizing parameters will be accurate.
