Awesome videos man, I appreciate that you do these. It is good to have a practical refresher to look at if I need a reminder of how something works. Besides I see you write your reports in crayon like I do so we are on the same page 🤣
Wonderful Paul I really enjoy all your videos, the way you explain is pretty clear and useful 😀 congratulations 🎊 and thank you so much for all this material!!! Go Canada 🇨🇦 jojo nice T-shirt 👌
Hey Paul, great video! Quick question, was always told the .06” hole should produce a -2 “d” rating, but I cannot seem to find that in the code anywhere. Have you ever heard of this?
Hi Oscar, never heard that one. It doesn't make much sense though. d=a-b-c. On the SDH, a = b. So then you're left with negative c. C is (SPD-1)*2. The SPD to hole at 70 is 1.7", so c = 1.4 dB, so d is negative 1.4dB. For 60deg, d is negative 0.4dB. And for 45deg, d would be positive 0.3dB.
Thanks I found this video very useful. Please make a video about how to perform UT sensitivity calibration for root indication accordance to API RP 2X Level C acceptance criteria 😊🙏
Good afternoon from Western Australia; I've been religiously watching Paul's videos for many, many moons and I always find something that I didn't know that I didn't know about UT, so thank you Paul for all your efforts. I am considering buying sonatest wave, and have been searching for a "6 months or 1 year" type of reviews to see how this instrument performs in real life situations. After all, UT testing is a messy business so I am wondering how this arrangement works where couplant is present and will inevitably transfer onto the screen, sometimes in quantities. Does this arrangement creates a limitation as far as controlling the instrument? I would appreciate any feedback from users, Thank you, Chris
The Wave has a pretty good resistance to couplant blobs. Physical buttons with a non-touch screen still have advantages, but in most cases the Wave layout (all screen, no buttons) wins out... unless you're in the messiest of situations and trying to press on the screen. You always need a clean fingertip or knuckle if you want to keep the screen blob free.
I think there is an error in the drawing shown in the AWS D1.1 standard (Figure 8.13-Typical IIW Type Block). The depth for a 50 mm diameter hole is shown as 23 mm. The sound speed equivalent of 23 mm Plexiglas is 50 mm for steel. AWS D1.1 block prices are high due to the error.😆😆
Can you talk about W59 reporting and surface cracks in HAZ zones? I had difficulties with how close some cracks are to the toe of the weld. Thanks. (From W59 CGSB exam)

This is really helpful, don't do a lot of AWS specific inspection here in New Zealand so will remember this when it crops up again

Thanks Holloway, last Few week ago I have told my client about the AWS setting that there is no DAC, because AWS uses the Ref SDH 1.5 V1 block

Hi sr, great video, do you considere, a video about paut in api1104? . Thanks
+1
Thanks Santiago, I need to learn more about it myself

This is very useful but i have a doubt How can you add scanning db ?
Its"This column refers to sound path distance; NOT material thickness....
Yes, so just look at the range you are using for inspection
Please explain AWS CLASS X and CLASS R INDICATION level sizing
Hello, I think probe resolution verification is missed here..
.
For sure.. that's why it's a general overview. Can't teach all the nooks and crannys of AWS D1.1 in 5 minutes.

In fact I might!
Some codes just seem to want to make your life hard on purpose :(
