If this is a fabricated test piece, I'm sure you have the data sheet for the indications and know the true origin of the defects. However, if this was a weld that has been in service, and without knowing a detailed history of the service, I would have called the second indication porosity. Was this data collected from a test piece or in service weld? Hmmm...

He sounds like the guy from all the Khan academy videos. Good info thank you.
i liked it technique, thanks Olympus NDT :)

Same as me, i thought it was a cluster of porosity until he said it's "Thermal .... Crack". Hope to get his explanation about this case?
please, have a video like that Explain Slag, Porosity, root concavity, root undercut, cap undercut, cluster porosity
GreatPresentation ! I am interested to become PHASED ARRAY INSPECTOR who is the approved trainer certifier kindly give me feedback!
Scanning dB didn't drop ?? Interpreted on
Ref dB+scanning dB??
Great Video!
