Why They DON'T Use Welding on Bridges

They still build massive bridges using this dangerous century-old technique called "hot riveting." Workers catch thousand-degree glowing rivets and throw them across the bridge, then a hydraulic press smashes them into place. The secret? As the metal cools, it shrinks and locks the steel plates together tighter than any weld or bolt ever could. This ancient engineering technique has been holding up bridges for over 100 years.
