Good sir

The side drilled hole should show a depth of .600” at calibration, should it not?

where can you find some defect? in between the first back wall echo or in the middle?

AWS on/off before calibration and after?

Thank you

Thanks alot

Very usefull ,keep it up ,Thanks alot

Thanks man !

Well done bro

Sir m/s velocity in ultrasonic testing

great job dear, Keep it up

Proffesional!

thank you John !

Great Job , Thanks brother

Thanks man ! great job

Thanks man, Well done !

downstream side? on plate ?

Sir.. how to identify this is Lack of root penetration or lack of fusion. just clarify

Sir..this is look like crack signal . I don't know how to identify this is slag inclusion.

Wonderful Sir 😊

this guys deserve a big respect!

Can some explain why is the 1/32" wide notch is used as a reference level and not the 1/8" diameter hole? Thank you.

you are truly an awesome Mentor Thank you John!

Thankyou so much ! 👏

My life is a lie... I've been doing wrong all these years 😂

I've been struggling with this calibration for years now, this video just opened my eyes. Thanks so much for making it so easy to understand... God bless you brother.

I am not understand.

How do you catch that with a backing bar?

Hindi

the repair wil always be in the root an its a same that a good welder brakes down... invent a machine that any welder wil have a peace of mine before weld that the other side has no defects before taking responsibility

can i ask question..if u scan for example 9.7mm base metal thickness ..how much is my range for scanning.im using usm35x .thanks for the response sir.

I call bullshit

Excelent!

Hello john. Thank you for you video. So i wanna know how to switch from UT mode to the PA mode manually in the Epoch 1000i?

Will a 45 degree give a better signal

This was a questuon on B cwi exam. Not sure if I got right:(

Hİ John Can you show phased array tvg drawing with epoc 1000i

Hi john I need c scan and record Can you show c scan with epoch 1000i

Excellent

What does it mean when you get a signal from the root from the side the transducer is on. But you can't plot it, because your beam path is way too high. And when you move the transducer to the other direction, there is no signal at all ?

nice

Just to add on this, if you wanted to measure the height of an imbedded crack, you'd need a top and bottom tip and measure the difference between those.

What was your screen range?

Sir tell me 1:1 diagram beam profile how to

Sir, pipe thickness 6.4 mm, dia 4".ut testing half skip catch one defect sir, but defect beam bath full beambath is coming, why is this happening, sir 70 degree probe use sir true angle 69 degree, but defect half skip and depth ok sir but beam bath only high full beam bath coming sir. Why sir. Please tell me sir

Sir how to drawing beam spread 1:1 diagram please one video sir.

Hi there! Just wanted to let you know how much I appreciate your videos. Just started learning UT and these videos are great! Keep them coming!

Please John make a DAC video and reiterate why we even need the DAC when doing ASME. I understand that we need to know how the indication acts at different depths. But I’m struggling with building them and also understanding why we would need it.

John you looking to sell this unit?
