I have some small doubts in UT
Download

1. There are calibration v2 blocks of 1.5 hole and 5 me hole what is the reason behind it is it only for better sensitivity or there were any other reson

2. While doing range calibration with v2 block I observed these things with Einstein modsonic 2 that while we faced the probe from 25 radius end of we clearly observe the depth it will be shown as 8.5 but where we given the thickness of the material as more than 8.5 but in the same case if the thickness is below it changes the value either 2 to 4.5 . Why?

3.what is the weld geometry for a pipe especially for double v saw weld
Pipe,

4. Is it really necessary to add the reinforcement of I'd and od to thickness of the parent material in the case where we using N5 notches (example coil thickness 15 and reinforcement is 1.5+1.5 so is iit mandetary to add 3mm to job thickness or not) .

5.can anyone share me the actual cycle time calculation ( I have doubt of taking the dia of the crystal as 8 or 12 for (8*9 rectangular crystprobe)

For 5 one just tell me what is correct. As we are facing 8' crystal and doing so we need to consider only 8 or as a formula we need to use 12 .
Just see attached link for my reference material and find page 449-56 page https://inis.iaea.org › _PublicPDF

Hi,
Answer for your second question..
When thickness is 8.5 or above, it shows tk as 8.5 means sound waves actually reflect at that point.
When it's below 8.5, tk will get reduce.. as machine trigonometry thinks the waves passing in the full skip which is not happen.
Here in m/c set tk as 7. Now waves after 7mm tk will be considered as it travels in full skip. So you will get tk 5.5.

Lyft™: Pulsed Eddy Current Reinvented

PEC Reinvented—CUI Programs Redefined Corrosion under insulation (CUI) is possibly the greatest u
...
nresolved asset integrity problem in the industry. Current methods for measuring wall thickness with liftoff, without removing insulation, all have severe limitations. Eddyfi introduces Lyft — a reinvented, high-performance pulsed eddy current (PEC) solution. The patent- pending system features a state-of-the-art portable instrument, real- time C-scan imaging, fast data acquisition with grid-mapping and dynamic scanning modes, and flexibility with long cables. It can also scan through thick metal and insulation, as well as aluminum, stainless steel, and galvanized steel weather jackets. Who else but Eddyfi to reinvent an eddy current technique and redefine CUI programs. Got Lyft?
