An Amazing Way to Build a Trunk Lid
This is so cool, it must be some sort of World War II Aircraft Manufacturing technique for welding aluminum by smashing it together that was used for cars. This trunk lid was made by Carrozzeria Touring in the late 1940′s and as much as I curse the way they build cars, this is some of the most amazing craftsmanship I have seen. Since it isn’t adding any new material its keeps the panel very light and super strong and without the heat of welding, the panel doesn’t warp and distort. I’m guessing that the force of smashing the two aluminum pieces together in a focused area causes enough heat to melt and stick them tight.
I’d like to see other examples of this attachment procedure and find out what it’s called.
