We congratulate our longtime partner Designwerk for the national Prix Watt d'Or!
We are also very pleased about their success because of the battery cool covers we produce which are installed in the E-Trucks.
The installed cool covers are manufactured with friction stir welding (FSW). Friction stir welding not only allows the welding of aluminium alloys, but also the joining of mixed joints such as aluminium/copper, aluminium/brass, copper/brass etc.
A rotating tool is immersed under pressure into the components to be welded and joins them together without additives. The connection is not made by melting, but by stirring the plasticized materials.
