Cytec technology inside
for excellent friction stir welding FSW
FSW head for CNC machines
The Cystir motor spindle and the 2-axis welding head are specifically designed for friction stir welding to create a perfectly fused conjunction between similar and non-similar metals.
As a result, the CYTEC friction stir welding technology achieves a perfect state of plasticity and a strong conjunction between different materials.

Automatic Tool Clamping system
Cytec Friction stir welding spindles and heads are equipped with an automatic hydromechanical tool clamping system and shear force transducer for an optimal force regulation during the welding process. The Flextool and CyStir motor spindle offers further automation solutions to seal the weld seam.
The tools are inserted either manually or by a pickup station into the tool interface.
The PLC triggers the hydraulic operation to lock the tool high clamping force.
The tool clamping is controlled by an analog volume flowmeter combined with an electronic evaluation device integrated in the control cabinet.

High surface finish, less process force and heat, highly dynamic welding enabled by non-rotating tool shoulder separate retraction of the Pin or separate pushing shoulder.
This special join process is more sensitive and a good alternative to great better surface finish. The friction pin rotates into the mate-rial. The non rotating shoulder gives a slight pressure to the welding surface. This process create less force and heat. This type of FSW tool is often used on thin workpieces. With the Flextool an axial shoulder compression at the end of the welding process is possible. During the shoulder stay on the surface the Pin returns from the material.

The force measurement is carried out by three shear force transducers which are arranged in tilt position by 120° each around the longitudinal axis. They detect any axial deflexion during welding over the full range of 360°. As a result in every situation a reliable and safe regulation of the processing force is guaranteed.

The zero point is adjusted to 12 mA so that a deflexion in both axial directions can be detected.
For determination of the force that impacts the FSW-tool, the evaluation electronic reports a summation of all three sensor values.
So radial influences can be filtered out. As a result a purely axial value is available for the regulation of the pressing force.
