Removal of weld from internal vessel surface 5

[KevinNZ]

We have a vessel that for the process requires a smooth vessel internal wall surface. Does ASME allow protruding weld metal be removed back flush to the vessel wall after the welding?

 

[IdanPV]

I thought that the discussion is about ASME not "other codes", isn't it?
Please share your knowledge, where in ASME VIII-1 it is written that NDE shall be done after grinding a weld?

Nowhere.

 

[DVWE]

I could be mistaken, but I think the code does talk about when to stop digging a hole; it’s in one of the mandatory appendices

Why not read ASME V?

ASME V states for RT, MT, PT only that surface irregularities shall be removed prior to testing.
After testing you can do what you want as long as you do not reduce the actual wall thickness. (see ASME VIII Div 1 reference below)

T-222.2 Welds. The weld ripples or weld surface irregularities
on both the inside (where accessible) and
outside shall be removed by any suitable process to such
a degree that the images of surface irregularities cannot
mask or be confused with the image of any discontinuity
on the resulting radiograph
T-642 SURFACE PREPARATION
(a) In general, satisfactory results may be obtained
when the surface of the part is in the as-welded, as-rolled,
as-cast, or as-forged condition. Surface preparation by
grinding, machining, or other methods may be necessary
where surface irregularities could mask indications
T-741.1 Preparation.
(a) Satisfactory results are usually obtained when the
surfaces are in the as-welded, as-rolled, as-cast, or as forged
conditions. However, surface preparation by
grinding or machining may be necessary where surface irregularities
could mask indications due to discontinuities

UG-99 STANDARD HYDROSTATIC TEST
(a) A hydrostatic test shall be conducted on all vessels
after
(1) all fabrication has been completed, except for operations
that could not be performed prior to the test,
such as weld end preparation [see U-1(e)(1)(-a)], and cosmetic
grinding on the base material that does not reduce
the actual thickness below the design thickness

And now that?
IS AN NDE REQUIRED AFTER PERFORMING FLUSH GRINDING ON THE BASE MATERIAL?

Good post, DekDee. But that horse named r6155 is already at the water trough, if you catch my drift……

DekDee confirms what I said in my first post: "Be careful, RT or any NDE must be performed after this removal."
Please note that hydrostatic testing is not an NDE.

@ DVWE
This is what I expect from you: aggressive
And now inconsistent: DekDee agrees with me

 

[DVWE]

Me? Aggressive? Sorry, I was just trying to be funny!

[DekDee]

And now inconsistent: DekDee agrees with me

The day I agree with you is the day I will cease posting on this forum.
I have said it before and I will say it again - you bring nothing constructive to this forum.

 

[r6155]

@ DekDee
You're confused again.
You are the non-constructive one, you don't respond to (OP) at all.
Didn't you realize?

 

[Christine74]

I have to agree with DekDee, r6155's posts have always been riddled with overgeneralizations, non-sequiturs, complete irrelevancies, and outright falsehoods but he can never admit error. I used to think he was trolling us but now I realize that there's something wrong with him cognitively speaking, and whatever that is it seems to be getting worse. His posts are becoming more cantankerous, less coherent, and more vague with no appreciation for nuance.

@ Christine74
You are one more who does not answer (OP)'s questions.
I haven't received your attacks in a long time.
I'm sorry you can't understand the manufacturing, welding and inspection issues because you have no experience in this. Your activity in this forum on these topics is null.
I can not help you.

[Christine74]

For the record the OP was answered clearly and correctly with the very first response before you highjacked the thread with falsehoods and gibberish.

Also notice that my name currently appears on the MVP list for this subforum and yours doesn't (nor will it):

Attacks? Wow…… would you like some cheese with your whine??

@ Christine74
Your participation here is evident: offensive, aggression, attack, ....etc.... towards me.
You don't respond to (OP).
