double-head friction welding machines are driven by servo motors that allow the angular position of their motor shaft to be controlled, as well as the speed of rotation and acceleration, since they are equipped with position sensors. If the spindles are controlled in the same way as CNC-controlled

As friction welding operates below the melting point of the materials, even dissimilar material joints can be produced with high tensile strength. In many cases, the tensile strength of the bimetallic joint is higher than that of the softer base material.
