I was thinking about welding but aluminium welding is tricky. This are just few things to consider when welding aluminium:
1. Welded aluminium is much weaker near the welds unless heat treated.
2. Tig aluminium welding requires major parts cleaning.
3. Aluminium needs raised seam. In my case because I attach aluminium panels from outside of the box frame I will need to grind seam down and this is a bad idea when it comes to aluminium.
Also when I build the frame I use 1 revet at each corner/ "T", so everything is still "flexible". Then I make sure everything is square and straight, then I add extra rivets.
Using hydraulic rivet tool I made makes riveting is not very time consuming.
If I decided to use steel for a box frame I would definitely weld it all.
