Some NDT technologies. Eddy current testing, can be used for welds amongst other applications. For working infrastructure (gas plants, refineries, oil rigs etc), Acoustic Emission, which detects growing defects (not non structural cracks or defects). AE can also be used for leak detection - it starts detecting at a molecular level - long before other detection methods. It is also used to test Carbon and glass fibre structures. X-ray diffraction can be used to test stress, and in 1 case I know off, crystal alignment/structure (jet engine turbine blades). Don't know if that is still being used. Rotating assemblies - Vibration analysis. Electrical and other faults - thermal imaging. Just a short list for anybody interested.
I was an NDT inspector, UT lvII and a CWI visual inspector did it in refineries and underwater. I'm surprised it's taken so long for someone to do something about it. There's a lot of vids about welding but not about N.D.E. cool do more about UT. And RT.
If they shot it panoramic they would have to remove the collimator which cuts the dose down significantly. Most companies don't commonly have 360 collimators. Without knowing their focal spot size, the Ug may not have been appropriate.
@@Welder_Danea . Ug is only a guideline. Final acceptance of radiographs is based on the ability to see the prescribed wire, Also , its right in the code that you must use source side pennies when accessible by hand, They used film side pennies. At 2 minutes a shot external i would assume they were using something of a D7 film and 30 curies. Thats a 15 second shot centered to shoot the whole weld , instead of 6 minutes of exposure time.
More videos on testing please because it's interesting to see how it's done and where welds can go wrong. Excellent video.
Thank you! I 100% agree there is hardly any videos on any of this!
@@Welder_Danea No problem young lady. Maybe as a certified welder you could put some welding videos on your own channel?
We have more videos on inspection and will be adding more! ua-cam.com/play/PLHyaWx2NbtgZxny8PaOW-_ci6RX-gLC76.html
@@JonDingle I’m definitely on planning on more videos! My reply to this video apparently didn’t post!
@@Welder_Danea l shall look forward to those then. Just make your videos better than my rough and ready videos and you will be a winner!
Love the inspection content! Keep killing it D!
Thanks! I loved sharing all this knowledge that most welders don’t get to see until they are out in industry!
Thanks for the refresher.
Great thing to learn about. Thank you.
Thanks!!
A lot of useful info on here!
Thanks. We have more and are working on more. ua-cam.com/play/PLHyaWx2NbtgZxny8PaOW-_ci6RX-gLC76.html

Right? Hopefully we can do more!

Welded pipe for 30+ years. Always dreaded unemployment trucks with a passion.
"Unemployment Trucks" took me just a 2nd, but I got ya.🤣
Go home truck
One of hard Test I have was getting the ll in PAUT ASNT but In the same time I found the pleassers I hope more video about the UT AND PA
25 years I did ndt north sea nuclear and shipbuilding. All disciplines.
Thank you for your service
Nice presentation
Thank you!
Why didn't the rt crew center pop that test piece? ALARA first always. probably would have been a 30 second shot and got it all at once.
Crew did not have a panoramic collimator

Mr. Andrewwwww ☯️💝😇🙏🙏💓💖❤️🔥🚀🚀 Mr Rick
Andrew was awesome! Knew exactly how to explain everything!
If you want to get into ndt field I hope you are good at math because there is a lot
Yes that is a very good point!
mechatronics engineering it excruciating.
Я работал сварщиком в компании crc-evans в России, скажите, сейчас они продолжают свою работу?
I can smell the spray can test stuff from here

Spoilt the video by playing music over people talking. Stopped watching. Do you play music to people you are talking to on the phone as well?🤦🏼
Nice presentation
