weldtek;
What is your application for asking this question? I reviewed Figure 16.1 sketches (a-1), (h) and UW-16 (c) 2. It seems clear to me with no real exceptions for attachment of separate repad plates. I will check any Code cases.
I have a 2.5" wall vessel, with a 2" thick repad.
This paragraph indicates that a 1.25" throat is required, say ~ 1.75" fillet, but, it calcs ok with a much smaller fillet, ~ .625". I agree that the paragraph is very clear, but, there's quite a difference between what compress says is ok and what this paragraph calls for. I'm wondering if there any exceptions to the rule.
I red the par. and 1" throat is required or 1/2Tmin (Tmin of 2") and there are any excemption to this rule.
I would not ask for more since the rule is already giving alowances.

UW16(C)(2)(a)was the paragraph in question as noted in the heading of the original post, and, which pertains to the fillet weld at the outer edge of a reinforcing pad. It calls for a fillet with a minimum throat of 1/2tmin. I had mistaken this for 1/2 of t, min. UW16(b) lists the symbols and their meaning, and says that tmin is ' the smaller of 3/4" or the thinner of the parts joined by a fillet...' In our case 3/4" is smaller than the plates attached by fillet welds, so, 1/2 of 3/4" is 3/8"/.707" = ~17/32". In our case we had used a 5/8" fillet, which was more than adequate.
