It was very interesting, take a plate of steel, and a plate of aluminium, and roll them thru a hotmill.
The millions of tons of force generated when passing through the mill cause the steel and aluminium to fusion weld together.
I wish I knew which ships received this product and how well it worked.
It was an extremely noisy process which we called thunderplate due to the noise of the plate moving down the roll tables.
The defence contractor would cut the plate into specific size and shape then weld the steel to the ships deck and weld the new aluminium superstructure to the aluminum side.
Hmm thats pretty cool. Never heard of that before. Learn something new everyday!
