Pre qualified Joint details, AWS D1.1

Pre qualified Joint details, AWS D1.1

Pre qualified Joint details, AWS D1.1

(OP)
Practice exam query: joint B-L2c-S (page 96), range of root face as fit up, base metal 1 inch thick.

Being timed I was rushing, and answered 3/16 - 5/16, as f = 1/4" inch max +/- 1/16".

Correct answer 0 - 5/16".

Obviously as a joint with complete penetration, bottom of tolerance for 'f' would be zero. (I think that is the conclusion to be drawn, anyway)

My question is, why do they stipulate the range for 'f' differently for SAW than for the other processes?

The next 4 pages have similar situations, cjp joints with 'f' stipulated as "0 - X" for all processes except SAW, where f = "X max." or "X min."

Why is it written for SAW as "1/4" max", instead of "0-1/4" as the same variable is formatted for the other processes?

Thank you.

Couldn't find it in AWS D1.1. I found a B-L2a-S.

That might be right. It was page 96... single v butt joint, no backing

Yup, it is on page 96.

Your guess is as good as anyone's guess.
