I'm practicing for D1.1 CWI code test and this question has me stumped.

"What is the effective size flare-V groove weld that the engineer can take credit for when two 3" bars are welded with GMAW the joint is filled flush?"

According to Code Clinic workbook the answer is 1 1/8". Referencing table 4.1

Table 4.1 says

Flare-V Groove

GMAW 3/4 R

Can anyone explain how the answer 1 1/8" was calculated?
