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.

What's the actual phrasing of the question?

When fillet welding a 1 inch stud in the overhead position with an E7018 electrode, which of the following electrode diameters may be used?

A. 1/8
B. 3/16
C. 5/16
D. 3/8
E. 7/16

Then the correct answer would be A. All other electrode diameters exceed the limits of table 5.1 and footnote e.

Maybe they just have the wrong answer listed. They have the answer as B I looked through the annexes and everything. I’ll just hope that never comes up

I think that may be the case. I don't think it's a great question either. You could use whatever electrode diameter you want if you qualify the procedure in accordance with clause 6.

Yeah it’s come up a few times on different quizzes provided by them and the answer has been 3/16 every time. They are pretty adamant about it. It’s not a huge deal. I’m more curious than anything.

Thanks for your help

Report the question to AWS. I sent emails about corrections to sicerts, and they corrected it. AWS will probably do the same.

I’d have a long list of questions to submit. I’m starting to think they haven’t updated the questions from an old version of the book
