[PSUBS-MAILIST] glueing aluminum

[Alan via Personal_Submersibles]

Hank,
they glue steel laminations together in electric motor stacks so 
I don't see why aluminium shouldn't glue together successfully.   
Depending of course how you are gluing it. If you are laminating
sheets together they should be pretty strong.
When I was searching for a pvc glue for sealing my penetrator wires
I tested a number of glues people suggested, but the glue that was 
used commercially on pvc boats won hands down. Worth researching
well.

The reason is that welding weakens the material, so if it were welded they would need to increase the amount of material and it would eat up the weight savings. Problem is, I don't know the specifics of the glue they use nor the process.
