[00:00:00]An indispensable method of joining metal structures in heavy engineering, superior to both bolts and welding. Hot riveting is a traditional connection used during repairs or construction on the most critical projects. A metal rod with a ready-made head on one end is heated to red hot and quickly inserted into the hole of the parts being joined, while a second head is formed on the other end using a pneumatic hammer or by hand. When the metal cools, the rivet contracts slightly along its length, tightly pulling the structural elements together. It is a type of metal clamp that is constantly under tension, so this connection is not affected by vibrations, does not weaken over time, and can last for decades.
