Inertia Friction Welding
 

【Inertia Friction Welding Cycle】

  • One work piece is attached to a flywheel – the other piece is held stationary
  • The flywheel is accelerated to a predetermined speed (RPM), storing the required energy
  • Upon reaching speed the drive motor is disengaged and the work pieces are forced together by a friction welding force
  • The kinetic energy stored in the rotating flywheel is dissipated as heat at the weld interface as the flywheel speed decreases
  • An increase in force may be applied before rotation stops
  • Welding force is maintained or increased for a time after rotation ceases

 

【Inertia Friction Welding Parameters】

  • Welding speed (RPM)
  • Kinetic energy (flywheels)
  • Weld pressure (PSI)
  • Forge cooling dwell time (seconds)

 

 

【Inertia Friction Welding Advantages】

  • Narrower heat affected zones
  • Shorter weld times
  • Ease of monitoring – RPM and pressure
  • No clutches, no brakes
