Rotary friction welding is a forge welding process, in which the heat for joining metallic workpieces is generated by a relative motion of two components while a load is applied. It works in the solid phase without reaching the melting point of the materials. Thus, even materials that cannot be joined by fusion welding can be welded. The weld region is normally narrow and shows a refined microstructure.

As a job shop we manufacuture batches, for which the procurement of a bespoke friction welding machine would not be profitable. Apart from steel-steel connections we can also produce dissimilar material combinations.
Based on our long-term experience, we develop suitable welding parameters and quality management procedures for friction welding.
Industrially manufactured friction welding machines are available from several manufacturers and are used commercially at several locations for the welding of cylindrical parts of all
AluStir conducts feasibility studies or contract manufacturing for you. In the case of high-volume production, we can advise you on machine specifications and machine procurement as well as quality assurance.
