Friction stir welding: 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 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 aluminum, magnesium, copper, titanium or steel can be joined with friction stir welding.
Friction stir welding: the advantages
Top weld quality
- 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
- 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
