FSW tools for Aluminium-Silicon welding The challenge : Aluminium silicon alloys contain silicon particles, which are very abrasive for tools and more particularly for the pin. This leads to very fast wear after a few tens of weld meters. Light casted alloys are used in context where mass saving are sought, such as automotive sector. This process is used for the manufacturing of engine blocks, heat exchangers, battery casings and wheels.

STIRWELD answer :
We have developped special tools for aluminium-silicon welds, which can weld more than 1000 meters in these alloys. This represents a 300% improvement.
