ULTRASONIC TORQUE TENSION TESTING
Perhaps the most critical element of success in bolted joint design is recognizing the limitations of using torque as an indication of a reliable joint. In most cases, particularly in structural joints, tension should be evaluated; torque is simply easier to measure.
Peak innovations Engineering uses the latest generation of ultrasonic sensor technology utilizing bonded sensors, allowing us to measure real-time bolt tension of your production bolts in your assembly. By establishing a fixed acoustic path between the sensor and the fastener there is no measurement variation due to coupling between the sensor and bolt.
A significant advantage of using ultrasonics for bolt tension measurement is it is the only measurement method not to require any functional changes to the joint or the fastener. Therefore, there is no risk the measurement method altered the test results. Ultrasonic technology also allows long-term monitoring of joint tension to assess stability in use or after dynamic testing.
Whether validating a new design, determining an assembly strategy or diagnosing a problem joint – contact the Peak team to find out how our high-tech methods of ultrasonic bolt testing can be put to use for you.
