What degree of tilt is acheived with FSW head?

Our FSW tool does not require tilting to ensure a solid weld.
When using our FSW head on a 5-axis machine, tilting can be done. The degree of tilt of the Stirweld FSW welding head is between 0.5° and 3°.
The purpose of this position parameter is to lift the leading edge of the rotating FSW tool. The tilt thus retains the material mixed by the shoulder in the weld area.
The degree of tilt is calculated according to the friction stir welding process.
