                • INQUIRY

                The equipment is used for thread fastening joint verification, anti-loosening monitoring, optimization of torque attenuation, corner method tightening process development and real-time axial force test. Furthermore, it is necessary to be provided with the ability to test clamp force in real-time.

                The various fastening parameters such as torque, angle of rotation, axial force, friction coefficient, torque coefficient, the calculation of bolt elongation during the tightening process is tested.

                The objective when simulating the actual assembly process on the aggregate for assembly experiment is to test the install performance of threaded fastener, threaded joint, and the development of assembly process as well as analyze the quality problems in bolt assembly.

                Bolt Pre-tightening Ultrasonic Testing System

                The bolt fastening axial, pre-tightening force, axial stress can directly be measured in real time through        ultrasonic. The value of time difference which between the intelligent bolt system launch and receive             ultrasonic pulse signal being calculated is called acoustic time difference.


                The  bolt axial force ultrasonic tester is widely applied in assembly testing domains such as automobile, aviation, aerospace, railway, wind power and nuclear energy. It has become a necessary testing instrument for bolt fastening system test and bolt assembly technology, providing strong guarantee for the R&D and design of bolt products as well as real-time testing and monitoring for the change of axial force.
