edfritsch,
in responce to your last question [ if your one inch interval started in center of the two holes ] then it would be unacceptable, that question was brought up during the cwi seminar that i attended, the instructor said that
you would add the total width of both.
Isn't a pore of porosity measured by its diameter and not its radius?
You can't make 3.5/32" of a pore of porosity magically disappear just because you draw an imaginary line through it. You can't just disregard what is on the outside of that line you drew if it's part of the same defect.
as i stated what the instuctor said we was not talking abuot a hole but elongated porosity
You'll always have a leg to stand on if you use that fomula no matter what method you are using whether it be MT PT UT VT or RT.
If you have a certain amount allowed within a certain distance and they all accumulate to exceed (reject) that amount then it needs to be a repaired. Or at least a portion of that distance needs to be fixed so the other defect is acceptable on the assumption that the repaired weld has no new defects that combine to reject it again.
If someone tries to make you accept something like that just step back explain your point and tell them that they can sign it off as acceptable if they feel like it. Guess what? They won't.
They'll get mad as hell , ranting and raving but if you can prove your point and that you acted in good faith you won't lose in the long run and it will get fixed.
I thought I was answering his question in in the strict boundaries that he asked it in but as I read closer after having a few beers I see I should have clarified a bit more - My rhetorical question was meant for him to see that ,as you state, porosity is measured by its diameter and not its radius and therefore the sum of the diameters of all visible porosity should be included regardless of how much falls within your 1" of measurement.
Thats what happens after a long day.
I would agree with g32141, and i might even try giving fractional fractions next time my boss wants a dimension! lol

If you have a valid point that makes sense you will never be wrong even if others disagree with you.
You must make sure that you are right beforehand though.

I tried to reply through some of the replies to your post but it was not possible.
It says that the original post doesn't exist.
Not sure how it works because I marked them all as read.
Your post shows up but I can't respond to it. I get a pink looking screen saying that the original post doesn't exist.
Edited for spelling and grammar
I think the key word is "any". Both indications are within an inch of each other so you would use an interval which included some of both making it unacceptable by that criteria. I dont have it in front of me. I am still a rookie CWI so wait for the veterans to chime in.
