There was a fairly long article in The Wall Street Journal on how the
car makers are using new kinds of adhesives to glue and rivet cars
together, to reduce weight. This is being done with aluminum and
steel. One problem with aluminum is that it's hard to spotweld.

"Super Glue Holds Your Car Together - Those Aren't Bolts Holding Your
Car Together", James R. Hagerty and Mike Ramsey, page B1 of the 9
September 2014 issue of the WSJ.

Unfortunately, it's behind a paywall, but just about every library in
the country gets the WSJ.

Thanks, Joe. I'll be using that one.

Often you can sneak up on a WSJ article without going through the
paywall. In this case, they've changed the headline of the article, so
it's a little trickier.

This does it. In Google or whatever, search on "Super Glues Are the
Secret to Making Cars Lighter." Use the quotes, or not. Try the WSJ
article. Usually, you can get in (I just did). There will be popups
asking you to subscibe but you can just close them.

Another joining method under development is laser welding. It solves
some problems they've had with conventional spot welding in AHSS
(Advanced High-Strength Steel).
