Friction welding is a pressure welding process. This technology can be used to join materials of the same type or of different types. KUKA established friction welding as an industrial joining process in 1966.
What is friction welding?
Friction welding is a solid state bonding process that produces high integrity, full contact joints. By rotating one work piece relative to another, whilst under a compressive axle force, the friction generated between the two faying surfaces produces heat, causing the interface material to plasticise. The compressive forge force displaces the plasticised material, extruding interface material and any contaminants, promoting molecular bonding, creating a homogeneous bond between the parent materials. With friction welding, no third party filler materials, flux or shielding gases are required. The process is machine controlled, 100% repeatable, with full in-process monitoring and quality assured.

Materials do not melt during the friction welding process
High speed, high integrity bonds
Machine controlled process eliminates human error
Highly suitable for quantities ranging: from single prototypes to high-volume manufacturing
Friction welds often cost less as no consumables required
Pre-weld preparations can be less critical for this process
Automated friction welding
Our flexible robot based systems allow for automated loading and unloading of our rotary friction welding machines, dependant upon your exacting requirements.
KUKA oﬀers a range of compact and modular friction welding machines with forge capacities up to 400 Tons for the ﬂexible implementation of friction welding processes, adapted to the parameters and fixtures applicable to the weld component.
If you aren't able to acquire your own friction welding machine, no problem. Have your welding carried out by KUKA's automation professionals on premise at our Halesowen facility. We have been carrying out subcontract welding work, developing components and producing prototypes for renowned companies since 1970.
