FSW: Friction Stir Welding

How it works

Friction Stir Welding is an innovative solid-state joining technology. The connection or weld is created by means of a rotary tool, consisting of a pin with a special profile. The material is heated by friction to a temperature at which the material is in the plastic state. FSW is a welding process where the melting temperature is not reached.

Friction stir welding is particularly suitable for joining materials with a low melting point such as aluminum, brass, copper, titanium …

If the thickness is less than 2 mm, we are speaking of micro-FSW.  In this case, a higher rotation speed and precise positioning of the work pieces is required.  The lower limit for the thickness is around 0.3 mm.


Friction Stir Welding FSW provides the main advantages in industrial manufacturing:

  • High welding speed
  • Economic process
  • High mechanical characteristic
  • Heterogeneous welding in various materials (Aluminum, copper, light alloys…)
  • High-thickness welding up to 100mm in one pass
  • No consumables…


Friction Stir Welding can bring interesting solutions.  We can easily weld homogenous multiple materials: Aluminum, Steel, Copper, Titanium, etc.  But also a combination of heterogeneous materials in various conditions like Al/Al (2XXX/7XXX, 7XXX/6XXX…), Al/Steel, Al/Cu, Al/Mg, Al/Ti.

We can count on a qualified research team that can help you in exploring the best solutions for your application through design and prototype testing.


We’re your partner in sub-contracting, providing FSW technology together with all its advantages.

We specialize in the production of single pieces, small and medium size batches on our FSW machines.
