Don't grind the cap below flush with the base metal.

I am wanting to take the longitudenal seam down flush. Are you saying this is not permissible by VIII Code?
I believe the code allows 1/32" undercut altho I would not allow it on a vessel.

If you're planning on grinding welds flush after hydrotest, I would get a buy in from both your AI and the customer inspector. Please heed all of the warnings above, 'cause these kind of things can go south quickly.
RE: Is cosmetic finishing of weld cap permissible?
Just need to grind down one seam and that would be before RT and before hydro test.
Thank again to all here, what a great forum!

Sounds logical. A defect extending upto certain depth below surface of the reinforcement can become exposed when you grind off the reinforcement. As far I understand, grinding reinforcement flush is desirable to prevent fatigue falure but should be done before any test.
