Process Steps for Rotary Friction Welding

Preheating Stage

When subjected to axial pressure, the metal materials come into contact. The rotating end rotates at low or high speed to press against the stationary end metal material. Upon contact, the rotational kinetic energy is converted into thermal energy through friction. As the temperature approaches the metal's melting point, the material enters a thermoplastic state.

Melting Stage

The continuously increasing axial forging pressure boosts friction kinetic energy, causing material temperature to rise steadily and the heated zone to expand. The melted material is extruded by the top pressure, with molecules diffusing and interpenetrating until the weld forms a unified structure. During this stage, axial pressure and feed distance are precisely controlled. Once the predetermined distance and weld dimensions are achieved, the melting stage is completed.

Welding Stage

During this stage, rotation must be paused while applying increased axial forging force to the components. This action aligns the metal molecules uniformly and fuses them more tightly together. Upon cooling, the components are forged into a single, integrated structure, thereby completing the rotational friction welding process.
