Rotary friction welding Rotary friction is a solid-state process joining two metal objects by applying rotational motion and forging pressure to the objects. High temperatures generated by friction, transform the point of contact into a plasticized state. This area is known as the weld interface. The pressure is applied to forge a metallic bond between the atoms of the objects. The overall molecular integrity of the original objects remains intact due to the narrow heat-affected zone of this tec

46K views · 126 reactions | Friction welding is a unique process where heat generated by friction fuses two metal pieces together, creating a strong and durable joint. This method efficiently joins materials without melting them, relying on mechanical motion to produce the necessary heat. | Interesting Engineering | Facebook
