Missed edge detected on final visual inspection BEFORE AUT - how to proceed iaw DNV-OS-F101
(OP)
In such case is a repair called and then proceed as per the repair procedure (and added to the repair rate) or is the repair welder authorized to grind open the missed edge, MPI and then manually fill out, followed by a pull of the line so that weld is in the AUT bay and the touch-up/weld repair is unrecorded. Who has the duty to inform the clients representative?

On this diagram (of a compound weld) there is a clear difference between what I term missed edge (LFS cap) and undercut (U/c Cap). I am an NDE guy but not a welding engineer but I believe the former has a different cause than the latter, and I would really appreciate if someone can give a very brief explanation of their causes. No parent material thinning has taken place with missed edge whereas there is definite thinning with undercut.
Also I wondered is anybody knew the Code evaluation and sentencing to DNV-OS-F101-10 but also out of interest to other codes. On this project im on which is auto-mig welded I saw the final weld station inspector call a welder over to profile by grinding and TiG repair the missed edge without it being called a repair. As stated this happened in the capping weld station so before NDT (AUT).
Thanks for your advice.

Thank you for your contributions to these forums. In a previous post (Magnetic Particle Indications thread330-153580: Magnetic Particle Indications http://www.eng-tips.com/viewthread.cfm?qid=153580 ) you referenced a pdf you were able to get through BINDT titled Magnetic particle inspection of precipitation hardening type steels written by C R Preston. It was originally published December of 2002 as Vol. 44 No. 12.
I am having a difficult time with possible false indications in 17-4 stainless steel, and I am hoping this article could assist with our testing.
You had indicated you could forward the article. Do you know the article I am referring to? If so, are you able to forward a copy?
Thank you for your assistance, Sir.

" ...able to get through BINDT titled Magnetic particle inspection of precipitation hardening type steels written by C R Preston. It was originally published December of 2002 in Vol. 44 No. 12 of Insight."
Where are you based? Have you tried to obtain a copy from BINDT, Northampton UK? IIts their copyright, so they are the first to approach as you have the details of the article, its author and which issue it appeared in.
Good luck
