PT requirement on root pass welding

[weldstan]

An NCR must be a true nonconformance and mmust be specified as to what part of the contract work is noncompliant. In your statement, the PT requirement proposed by the NDE guy is not a part of the contract. If the QA/QC department dictates how the work in the shop is to be performed, so be it. However the "NDE guy" is not the QA/QC department and the department can over rule the "NDE guy's" position as well as can management. Your hypothetical arguement is not really relavent to any of the Code shops that I have been involved with in 40+ years or the Qualty plans that I have co-written for a number of major EPC companies.

As the responsible Engineer, I have required root pass PT in specific instances and have specified and written the PT procedure to be followed.

Goodness, you seem to have a lot to say, but unfortunately most of it is nonsense. An owner can ask you to build something to any standard they wish as long as it doesn't contradict any jurisdictional requirements/laws. As r6155 stated, it is a standard, not a Code...it is not mandated. If you think an AI cares about what is in the NACE standards, you are completely wrong. They care about the Code of Construction....period. They do not enforce any standards.

An NDE company that is hired to do a job has no right to stop any work. NDE contractors are not the QC department. What exactly is the non-conformance here? If an NDE contractor tried to issue an NCR, I would laugh in his face.

Have you ever worked in an ASME shop? Written a QC Manual? Gone through a tri-annual review? Most of us replying to you have, and we see through your fluff.

I think you all have given the OP some good advice, whether or not he heeds it is on him.

Two things to consider, he is new to the forum, and his country code is SG which I believe is Singapore.

Personally, I have never done business over there, but the fact of the matter is they play to a different set of rules. That much might help explain a little...

The devil is in the details; she also wears prada.

1) your post 08Aug 23 “…......but as I know ASME allows certain cracks........”
I dont know if any crack is allowed in ASME CODE for pressure vessels.

2) QA/QC, NDE, etc., etc. they cannot reject any work. The engineering team decides whether to repair or continue with the work. The client must be informed and the agreement is normal to occur. On several jobs I have specified the Acoustic Emissions Test (see ASME V) during hydrostatic pressure testing. Crack is detected. I don't trust some inspectors.
I worked during the construction of nuclear service equipment (approximately 1986) and QA/QC could not carry out an inspection in shop fabricator without my presence (engineering team).
