The hybrid friction welding cycle is a type of rotary friction welding, and is a combination of the direct drive process and the inertia process. The direct drive process has a constant energy input using an electric motor. The inertia friction welding cycle, on the other hand, has rotating flywheels that store the energy needed for the weld, which makes it a fixed energy cycle. Hybrid friction welding is a combination of both.
The Hybrid Process
Why use the hybrid cycle? When working with a large diameter tube, which could potentially be a high torque application causing stress on the motor, the flywheels provide the benefit of making sure the motor doesn’t stall due to excessive force.
Conversely, when working with a very thin-walled tube that could easily be crushed or damaged due to excessive torque, a low forge force can be applied to ensure there isn’t excessive torque at part contact. This ensures the part can be welded correctly without distorting it.
The hybrid friction welding cycle provides flexibility to use these different variables and optimize the welding process for a particular application. This opens the door for much more challenging applications with one technology.
