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

No flames. No filler rods. Just pure physics at work. ⚙️ Friction welding is one of modern engineering’s most fascinating breakthroughs—where metal is fused without fire. Instead of melting materials with an open flame, this advanced welding technology uses pressure and high-speed motion to generate heat through friction. The metal softens just enough to form high-strength metal joints, while preserving its original structure. This flame-free welding method produces joints often stronger than co
