B31.3 -2008 341.3.4 (f) 2

[katty11]

Does anyone have a clear understanding of 341.3.4 (F). this is part of the progressive sampling for examintion. I understand this as
during sampling you have one bad weld
you shoot two tracers 341.3.4(a)
one trace is bad 341.3.4(c)
you shoot two more tracers then
you repair those items until it meets code requirments.

any thoughts?

I think that I understand your post, but I fail to understand what your question is. Please phrase your question in the form of an actual question. "Any thoughts?" is not sufficient to generate any useful responses. What information are you trying to extract from the engineers and their broad range of experience that resides on this site?

Sorry, you are correct, let me re-phrase

Does anyone have a clear understanding of progressive sampling for examintion 341.3.4 (F).
I understand this as
during sampling you have one bad weld
you shoot two tracers 341.3.4(a)
if any of the tracers are bad 341.3.4(c) you shoot two more tracers and if any of those tracers are bad you continue shooting tracers 341.3.4(e)until you have covered all the welds made by that welder with that process or untill all the x-ray meet code requirements.

Does section 341.3.4 (f) lead me to undertand that after i shoot the two tracers in accordacne with 341.3.4(c)& (e) that all i have to do is keep repairing that weld 341.3.4(e) untill is passes code requirments?

Item (f) would appear to be exclusive of the other items, i.e. it is not contiguous with (a), (b), (c) etc. It follows straight on from the first sentence. But, essentially, the other items will allow you to carry on repairing and reexamining to your heart's and bank balance's content.

In summary, the first time you examine a weld and it fails, you must shoot two tracers but the second and subsequent times that same weld fails, you do not have to shoot tracers.

The maximum number of tracers necessitated by any one weld is two regardless of how many times that one weld is repaired and re-examined.
