Friction Joining - Including External & Internal Flash Removal
Continuous Drive Friction Welding
In continuous drive friction welding, welding heat is obtained at the joint by rotating one part against the other at a constant or varied RPM, with an axial force applied to the mating components. Energy is provided to this joint from a continuously running prime mover - usually an electric motor, directly connected to the machine spindle. This energy source is infinite with respect to time, and is supplied to the interface until the proper total heat is obtained. When this point is reached, the rotating member is stopped and a forging load is applied to the parts to be joined.
