Gluing aluminum

Sometime back I watched a show about building the new Maserati, Bugatti? They built the frames out of aluminum and glued and screw the frame together, the screws just holding things together until the glue dried. What type of glue is this?
It seems to me is it will hold a car frame together it should be strong enough for a metal working machine. Mite be I just have to many pie in the sky ideas.
