## AWS-CWI part B question

hi
could any body help me in some question on cwi part B because I become confused

1- what is the maximum convexity of a 5/16" fillet weld ?
A-1/16
b-1/8
c-3/16
d-5/32

as per part B book my answer is A because in book written IF W>= 5/16" the convexity equal to 1/16
But the correct answer is B 1/8 how coms ??

2- what is the minimum and maximum groove angle and root opening of a B-U2-S joint in the as fit up condition ?

A-20-30 and 5/8 - 11/16
B- 15-25 and 9/16 - 7/8
C- 15 - 40 and 9/16 - 15/16
D- 10-35 and 1/16 - 1/4

1 Note: The effective throat of a weld shall be defined as the minimum distance from the root of the joint to its face, with or without a deduction
of 1/8 in [3 mm], less any convexity.

Question (2) I answer tomorrow .

@sam906,
look in this pdf.1234-AWS D1.1-2010.pdf

sam906,

STOP!!!

If you try to answer the "Part B" questions with answers from AWS D1.1 you are going to FAIL!

That is why "Part B" says 1/16 instead of 1/8.

"Part B" is a code that AWS made for the CWI test. It has slight variations from codes used in the industry.

If you look closely you will see other differences as well, such as with the acceptance levels of undercut. The AWS D1.1 answer is not the same as the "Part B" answer (At least it was not when I tested).

They do this to test one's ability to use a code they are not used to.

So for the "Part B" test, forget everything you know about AWS D1.1, shut and put away AWS D1.1 and use "Part B" and the answers within.

sam906,
I do not have access to my old Part B book. I tested in 2003 and it is at my home in Colorado. I am currently working in Tulsa OK.
