ASME Codes : NDE PV weld examination

[jodipedro]

Hello everyone,

I would like to have opinion about books that simplify and/or have the ASME codes on Pressure Vessel; specially about application of NDE TOFD method on PV welds.

Here some links I already got from my other forum
(thanks to waskillywabbit and metengr), which one is better for application of TOFD NDE method with ASME codes(then I'll buy one!!):

1. The ASME Code Simplified "Pressure Vessels" by R. Chuse and B Carson (an excellent book on code rules with an in-depth section on welding).

2. Pressure Vessel Design Handbook by H. Bednar

3. Pressure Vessel Handbook by Eugene F. Megyesy

4. CASTI books on Section VIII pressure vessels

Regards,
Jonathan, jr.ing.

jodipedro;
If you want information on UT time of flight diffraction (TOFD) you need to talk to a vendor directly. My first suggestion is to contact Structural Integrity and Associates or AEA Technology; they can send you various technical articles on the TOFD method; you will not find this NDT method described in any detail in the books above.

you will not find this NDT method described in any detail in the books above

for good reason.

the application, effectiveness, and usefullness of TOFD has a narrowly defined window of reliability. yes, it can provide valid NDE results; within its defined application.

other NDE methods for inspections (and manufacture) of PVs provide more depth and reliability than TOFD on the whole.

as with any NDE method, it should be studied and determine its suitability for your purposes.

TOFD is approved as a replacement for radiography of welds in new ASME Section VIII pressure vessels per ASME Code Case 2235. It is in fact more accurate than radiography, in detecting and sizing flaws, and is used by some to essentially fingerprint the welds during construction, so that flaws detected after a period of service can be compared to those found during construction to check for growth. Some infomtion can be found in the Veritec Sonomatic (formerly AEA)website
