Did you know there's a way to join metal parts without using bolts or welding—yet it's incredibly strong? It's called hot riveting. The rivet is heated until it's red-hot, then inserted through the metal parts. While still hot, one end is held in place while the other is hammered flat. As the rivet cools, it shrinks, pulling the metal parts tightly together. This creates a strong, lasting bond—perfect for heavy-duty structures like bridges and steel frames.#technique #tech #technology #rivets #metal #construction #facts #education
