I would like to present the following question to everyone:
Background :
I have a new piping system with a design of 2 psi vacuum. The material is SA312 type 254 smo. First round of x-rays failed. First repair complete. Re- xray fail.
Question:
The weld will be repaired with me observing everything. The old weld will be removed completely. May I follow the principles of an In-process Examination including dye penetrant testing of the root, hot pass and cap in lieu of radiography?
Please advise..... Richard Schram
