Kenneth, aluminum welding would certainly be my first choice. With that said, so many KR builders don't want to use outside contractors in their construction. One of the construction parameters in designing the tank construction process used in Mark's tanks was the ability of the average KR builder to construct these tanks in his shop. Thus, the use of Proseal for leak integrity and rivets for structural integrity. These are both very well proven methods in tank construction.
Another criteria was the ability to use the thinest material possible but still maintain adequate structure. I don't know enough about welding aluminum to even say whether you can weld weld .032. Remember, you want it as light as possible but not to the point of infringing upon structural integrity. I know Steve Eberhart is finishing contruction of his second tank, maybe he could chime in. Proseal is messy and smelly but I totally final constructed Mark's second tank on a Sunday late morning and early afternoon. As I remember, it took me 3.5 hours. Like childbirth, it's a pain you forget.........or so I hear.
