Friction stir welding (FSW): the process
Friction stir welding is a process in which a rotating pin is traversed along the contact surfaces between the workpieces. The frictional heat plasticizes the material, which is welded together.
The FSW process is particularly suitable for joining non-ferrous metals with a low melting temperature and for mixed-material joints. Even materials that are difficult to weld or dissimilar materials such as aluminium with magnesium, copper or steel can be friction stir welded.
The Friction Stir Welding technology is ideal for sealing of a battery housing
The friction stir welding technique has proven to be an optimum joining technology in electromobility.
Friction stir welding offers a number of advantages over conventional arc welding processes.
FSW ensures top weld quality
FSW guarantees cost-effectiveness
- No welding defects such as pores or cracks
- Joining of a wide variety of materials possible
- Comparatively low heat input
- High seam strength with minimal welding distortion
FSW is labelled as "green technology"
- Economical joining of complex 3D geometries
- Material savings through component optimization
- No consumables such as shielding gas or filler wire
- Environmentally friendly thanks to low energy consumption
- No fume extraction or anti-glare measures required
White Paper: Welding aluminium? No problem!
Aluminium and aluminium alloys play an important role in e-mobility because of the ideal combination of lightness and strength. In welding and joining processes, aluminium has high demands on the processes used. With comprehensive process know-how and the right
products, we make you fit for the technological transformation towards e-mobility. The example of the battery box shows how robots enable the production of aluminium components at the highest quality level;
