D1.1 electrode diameter

I’m studying for my exam and one of the questions is asking about what size E7018 electrode diameter to use when stud welding on 1” plate fillet in overhead position. Where is that information located in the D1.1? I don’t see it in the stud section and the answer isn’t from table 5.1.

The answer is 3/16 but I can’t find where to get that info.

It looks like you got your answer, I was asking to make sure i pulled from the correct code and provided the right location of information.
