Hi All,
It's bee awhile since I posted, but I have a question I am unsure of.
We are fabricating an aluminum weldment, 6061-T6.
Outer shell is Ø16.25" O.D., 1/4" thick rolled and welded tube.
On both ends is a flange that is .88 thick, that slips into the tube .38" deep.
Please see attached sketch.

Our WPS is qualified to 1/2" thickness for groove welds, I'm thinking even though we are only welding a 1/4" thick joint, the WPS doesn't cover the thickness of the thicker member. However, I cannot find in D1.2 (2003) where is says anything about welding different thickness materials, which leads me to believe our WPS will not work for this application. Am I correct?
Thanks
