Friction welding
Friction welding is a special type of press welding in which
the two surfaces to be welded are rotated relative to each other,
and compressed with appropriate pressure.
On the contact surfaces, the metal heats up due to friction,
becomes ductile and then thanks to the influence of heat and pressure a
cohesive, atomic-level bonding emerges. With friction welding, complex geometry
parts can be assembled from simple elements. Within a part
also substances with different chemical composition and mechanical properties can be found which wouldn’t be possible to combine with other procedures.
The use of expensive materials can be limited to the justified place of the workpiece.
The technology is mainly used in series production, such as in the automotive industry,
in the manufacture of hydraulic components, in the manufacture of tractors and agricultural machinery.
It provides benefits in general mechanical engineering and many other areas
