Ensure bolt reliability with ultrasonic verification

Bolt-Check is a state-of-the-art ultrasonic measurement device that allows fast and accurate inspections of bolted joints. Its intuitive user platform, ultrasonic technology, and traceability system let you instantly locate bolts in your database and appropriately schedule service and maintenance.

Bolt-Check is suitable for most bolt types and requires no special pre-treatment of the bolts. It can play an important part in maximizing operational time and minimizing failure. Bolt-Check provides a cloud solution with an intuitive bolt management database to store, sort, and examine measured bolts.

Ultrasonic measurement explained

Bolt-Check uses ultrasonic technology to accurately measure bolt elongation, a crucial indicator of whether the correct clamping force has been achieved.  A small transducer sends a sound wave through the bolt and measures how long it takes for the echo to return. This return time reflects the bolt’s ultrasonic length.

By comparing the ultrasonic length before and after tightening, Bolt-Check determines the bolt’s elongation. To ensure accuracy, the system automatically compensates for temperature changes that affect both the bolt’s length and the speed of sound in the material.

Because ultrasonic length changes differently than physical length, Bolt-Check uses a built-in, material-specific stress factor to convert the data into true physical elongation. The result is a reliable, fast and non-destructive way to verify preload in bolted joints.

Traceability and cloud-based data management

A traceability tag equips each bolt with a unique ID, allowing full traceability throughout its lifecycle. Technicians can scan each bolt tag using Bolt-Check and the RFID pen to immediately access its measurement history and identification data.

All measurement data is automatically synced with the web app, a cloud-based platform for managing bolt projects, storing records, and sharing data. When connected to the internet, the Bolt-Check device continuously syncs with the web app to ensure all documentation is complete, organized, and instantly accessible from anywhere.

Vestas improves bolt tightening with ultrasonic verification

“By using Bolt-Check as a documentation tool, we are able to investigate how the reality and calculations of the installation process align. R&D Test Systems can provide a solution that goes beyond theoretical calculations by using the Bolt-Check tool to provide actual data from the construction site,” explains Peter Bækhøj Schandel, Blade Bearing Engineer at Vestas.
