Control of screws and bolts tightening takes a growing importance in different sectors, where assembly defects caused by insufficient, excessive or heterogeneous tightening could induce hazardous consequences.
To avoid or mitigate the failures related to tightening, the measurement and the control of tightening pre­tension should be performed in order to ensure perfect sealing as well as assembly stiffness which allow withstanding external static and dynamic solicitations.
This paper presents the implemented technology, principle of the ultrasonic measurement and some industrial applications.
