FLEXTOOL


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.

Force regulation with shear force transducers

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.
