Welded connections for aluminum
Welded connections for aluminum
(OP)
I am having trouble coming up with allowable stresses for welds in aluminum connections. I have the 2000 Aluminum Design Manual, but there is no information in there regarding welded connection allowable stresses (unless I am missing something), only welded built-up members. I know the member changes allowable stresses if it within an inch of the weld, but I can't find anything on the weld itself.
Does anyone have any information on this topic or can you steer me in the right direction?

Try this link for any welding code or standard.

The D1.2 codes' section on design is minimal, about 3 pages. The reference I noted above is noted in the D1.2 code in Section 2 - Design of Welded Connections.

It is in the 2000 Aluminum Design Manual. Sorry, I'm at home so I don't have the ADM handy. If I remember next week when I'm at work I'll tell you the section. (In other words your out of luck.)
I think I've seen you post several questions about aluminum so I assume your new to its design. Let me give you some advice on aluminum welding . . . don't. Just kidding, but seriously, where I work we avoid welding critical members like the plague. Our shop makes racks to store material for themselves (not sold) so they are not "engineered". I don't think I've ever seen one without a crack in at least one weld. FYI, the material is 6061-T6.
This is just anecdotal evidence to file in the back of your brain. Yes, I've been to the Smithsonian and NASA and have seen the beautiful aluminum welds on critical components like rocket engines, so it must be able to be done correctly. I'm just saying be careful 'cause it can sure be done incorrectly.

Good luck.
For two common alloys, 6061-T6 and 6063-T6, the allowables are 15 and 11 ksi respectively, but again, you should check the provisions for applicability, as thickness, proximity, and other issues may prevail.

boo1, 2000 ADM is the 2000 Aluminum Design Manual.
