Assure Bolted Joint Integrity with Ultrasonic Testing

Ensuring dependable and long-lasting bolted joints is a critical aspect of manufacturing across industries. As technology continues to make an impact in quality assurance, we take pride in offering ultrasonic bolt measurement technology, that helps our customers push the boundaries of innovation. This advanced solution offers unparalleled precision and insights, helping industry leaders achieve optimal fastener performance and integrity. 

Why Ultrasonic Testing is a Game-Changer 

Traditional methods of testing fasteners, such as load cells, often require changes to the joint, which can compromise the overall setup. With ultrasonic testing, you gain a non-invasive and precise way to measure preload force, enhancing your manufacturing process at every step. Here is how it works: 

• Precise Measurements in Real Time  Ultrasonic testing utilizes acoustic signals to measure the exact length change in fasteners when under tension. By comparing ultrasonic signal runtimes before and after tightening, you get a highly accurate measurement of the preload force—critical for ensuring bolted joints remain secure over their life cycle. 

• Diagnose and Prevent Failures  This technology is particularly effective in recognizing potential problems, whether it is screws breaking or joints loosening. Visualize data on interactive graphs, identify yield points, and calculate precise torque strategies, enabling you to optimize processes and prevent costly failures in the field. 

"A lot of people base their tightening torques off of a percentage of yield.  So that's really beneficial for customers to see where the bolts are actually yielding,“ says Andrew Benson, Application Engineer.  

• On-Site Solutions  One of the standout features of Bossard’s ultrasonic preload measurement service is its mobility. Testing can be conducted on-site, without disassembling the joint—making it ideal for applications where downtime is not an option. 

Real Benefits, Backed by Expertise 

Ultrasonic testing is not just about precision; it is about performance and reliability. From agricultural machinery to industrial equipment, understanding exactly how fasteners perform under stress is crucial for manufacturers who demand excellence in their products. 

For example, by measuring input torque, thread torque, and tension, our engineers help you evaluate the true quality and strength of your joints. This can mean the difference between durable, high-performing fasteners and unexpected, costly failures.
