What is the strong of friction stir welding?

The welding force is the pressure exerted by the robot or the machine during friction stir welding operations. The force control is one of the most important elements for a quality FSW weld.
The friction stir welding force is measured in kilo Newton . The applied force is calculated according to the thickness, the material, the welding configuration and the workpiece. The maximum welding force is defined as the maximum pressure that can be exerted by the tool without causing permanent deformation of the materials to be welded.
The FSW process involves constant pressure on the workpiece. The FSW head is therefore equipped with a force control system which, coupled with the position control of the machining center, guarantees a quality and repeatable FSW welds.
