Hi Charlie- Agree with Pauul- John Drurys' book is good =- used to work with him many yeatrs ago.
Theres a lot of info for free on: https://www.nde-ed.org/EducationResources/CommunityCollege/communitycollege.php

The only thing I disagree with Johnn Drury is the use of rectified waveforms - best practice at the time but technology has moved on. Better to use unrectiied waveforms ( especially in thin materials ) easier to discriminate between echoes, Also betteer to use UT sets in broadaband mode for composites- attenutate the higher frequencies - so sometimes you pout in 5 MHz waves but the echo comes back at ~1 MHz - will not see it if you apply a narrowband filter.

Re John Drury book,

much of this is available on line for free in "Back to Basic series"

see www.silverwingndt.com/downloads/technical/Article1.pdf

just change the article no. to get other chapter eg Article2 , 3 etc.

I appologise for my apalling spelling earlier I shoud make sure I am fully away before posting anything.

Chris

Drury's book is great! In addition, I recommend Andrew Cunningham's book - 'A Practical Guide to UT in the Real World' - to learn various sizing techniques.

Any of Ed Ginzel's books as well as the above mentioned authors Cunningham,and Drury are very good . I lean more towards Mr. Ginzel's writing.

Chris, I totally agree about the use of RF vs fully rectified waveforms. This not being a very well taught piece of the theory, I was basically unaware of the purpose of half+ or half- until measuring internal corrosion on boiler tubes. Now, using RF or a half-rectified view is the only way to go for thickness measurement.

The Drury book is great, Andrew Cunningham's book is one of the best practical books I have come across.

I too have not used a rectified a-scan for any ultrasonic examinations, be it for thickness or flaw detection for the better part of 20 years.

There is so much information in the RF waveform that is lost to rectification. I know that I am an enigma amongst my colleagues, but I stick to the RF display for all of my UT examinations.

Dear Csaba, could you suggest me some papers in order to improve my knowledge on RF interpretation?

I don't think, that a paper will be helpful. May be only a book describing such things as interference, diffraction, etc. The best thing is experience: testing with different objects to gain some insight, how the wave changes due to the different circumstances.
RF signal is delivering full information. Signal processing (simple rectifying with some filter is such processing) will loose some information. Signal processing can be very useful (and even necessary) in automatic applications, but I think, that in manual testing the use of rectified signals is only a bad tradition, based on the old technique, that was not able to show RF signals.

Pablo,

Yes, I know where this figures come from:
They are copied from the so called Krautkramer pocket book (blue book) written by me.
In the original German edition of 1975 they were printed on page 69.

There have been several reprints in different languages, only some of them with copyright, that means with my permission.
There are no more reprints available from the company, i.e. from the successors of Krautkramer's.

With best regards

Udo Schlengermann

My favorite is Ultrasonic Testing of Materials by Krautkramer. It is the Gold Standard.
