Would welding a disc mount onto an aluminium frame effect the strength much? I seem to remember something about aluminium frames needing heat treatment and being welded upsets this. Its on a frame I've seen for sale not something I'm thinking of doing BTW.

7005 should be fine, although I've had good success with low stress components in 6082 without heat treatment. Just make sure you use the correct filler rod.

On the Easton website there is a PDF on fabrication.

Gives you all the information you need.

Sorry forgot to mention, you'll need the part thats to be welded to be of the same material. You can't weld 6082, 6061 etc to 7005.
