Could hollow-rivets(pop-rivets) be used to join the sheets?.I presume it might need a sealant to make it gas-tight arohnd each rivet.
What do you think?.

If you make the electrode holders long enough you could reach pretty deeply into such box-like structures. Of course, you'd have to bend a flange at the edge of the perpendicular sheet; you can't spot weld an edge to a flat surface.Larry Cottrill wrote:It isn't all that easy to weld an interior steel partition between two parallel sheet faces. I could probably do it by drilling a zillion little holes [imagine a row of holes where you can see the edge of the sheet partition at the bottom of each hole] and sort of blending closely neighboring plug welds together. Right offhand, that's the only method I can think of that I could actually do.
I'd really like to see this thing tried.
