Welding isnt an option anymore, as they are glued @ present.
But as said before, the sheer and peel strength of the glue is a lot higher than the failure treshhold of the aluminium itself.
So I concluded, according to the specs, the aluminium would break/bend before the glue would fail.
Structural glue is used in aeroplanes and cars, both for aluminium and steel
sheeting and depending on the kind U use u have upto a 40 year waranty.
I only use the glue on the frames, because they have a big surface to apply the glue onto, which gives the very high strength numbers.
The other parts will be welded, as they are known as "weak link constructions" because they have 90 degree connections.
