Linear Friction Welding is a solid state welding at forging temperature. The heat is generated by the friction.
The process is generally divided in 4 phases:
- Contact: the 2 parts are put in contact
- Conditioning: pressure is applied and oscillation motion starts
- Burn-off: pressure and motion are still applied and the material is expelled
- Forge: oscillations are stopped and pressure is held during cool down
Benefits of the linear friction welding process
- Excellent mechanical properties
- High productivity
- Guaranteed process quality
Near net shape manufacturing improves buy-to-fly ratio and reduces machining costs.
