Friction welding
Friction welding is a special way to join two things together, like when you want to connect two pieces of metal. Imagine you have two toy cars made of Lego blocks and you want to join them to make a bigger car.
Friction welding works by rubbing the two pieces of metal together really fast until they get very hot. Remember how you can make your hands warm by rubbing them together quickly? It's kind of like that, but much much faster and hotter!
When the metal pieces get really hot, they start to become soft, almost like melted chocolate or play dough, but only in a small area where they touch each other. This soft part is called the "plastic zone".
Then, while the metal is still hot and soft, we push the two pieces together with really strong force. It's like when you push two magnets together, they stick, right? But instead of magnets, we're pushing the metal pieces together.
When we push the pieces together, the hot and soft metal gets squeezed and mixes together just like when you squeeze and mix different colors of play dough. This mixing and squeezing makes the metal pieces stick together and become one piece.
After some time, we stop pushing and let the metal cool down. When it cools down, it becomes hard again, just like when you put your melted chocolate in the refrigerator. And now, the two pieces of metal are joined together and they won't come apart!
Friction welding is great because it doesn't need any glue or bolts, and it can join different kinds of metal together. It's like magic, but it's really science!
