You could totally connect an ultrasonic machine like this to a CNC arm and go over materials like a grid with a preliminary scan to scan large parts and then bring in an engineer afterwards to investigate the anomalies.
It depends on how big is the area of interest, if you are inspecting a weld then there is no need to scan the whole area, but if it is a composite removed from autoclave or press, then you should check the whole area as the defects can occur anywhere.
Excellent explanation. Thanks for sharing. If i may ask, is there any limitation in the product/specimen thickness. say, can I use this for 3mm thick weld specimen, to see a 0.3 mm crack depth. Appreciate any response.
Hello Prasan, Thin materials can be hard to test. A general rule of thumb is that a discontinuity must be larger than one-half the wavelength to stand a reasonable chance of being detected. Wavelength=Velocity/Frequency. Please click on this link, it may be of some help. www.bindt.org/downloads/NDT2012_1A2.pdf
@@pietpompiepompiepiet940 Yes, Magnetic Particle test would detect this flaw. MT will detect defects that are open to the surface and defects that are very close to the surface of the part.
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 ?
@@mohamedkamel2409 Yes cheers Bud !! ... I asked it, because it showed up on my PCN exam. The signal haunted me a little bit, because it was my third re-test. I knew it wasn't anything so I didn't called it ... guess who passed his exam ?
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

@@johnnyb28227 Hi. Would magnetic particle test also showed defect?

@@johnnyb28227 thanks for reply. What is the thinnest thickness I can use the olympus to detect flaws?
@@pietpompiepompiepiet940 ASME section IX recommends minimum thickness to perform ultrasonic inspection is 6 mm.
Thank you for this video. I really enjoyed it.
Thank you
Thankyou so much ! 👏
How do you catch that with a backing bar?
Nice brother... IP ND IF SLAG
downstream side? on plate ?
In the other videos thankyou so much
Please Explain pipie scanning tenique?
Can you demonstrate to us the signal of high low weld specimen
Nice video Sir

That could be mode conversion from shear wave to longitudinal wave

Can you test Spring
nice
Wheres our signal from the half skip of the weld and full skip of the weld??
how mach ref
level db
What is the coast of for one joint of 500 mm dia pipe?
I want to know UT test charges.
How to make sure that we have amplitude from indication, not from geometry ?
By calculating the sound amplitude, then bring the result to the drawing plot
