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
  • Conditionning: presure is applied and oscillation motion starts
  • Burn-off: pressure and motion are still apllied and the material is expelled
  • Forge: oscillations are stopped and pressure is hled 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.
