Bolts, like any other structural component, are susceptible to defects such as corrosion and cracking. In order to comply with safety regulations and to maintain structural integrity, these bolts are required to be inspected and if defective, monitoring and/or replacement would be required.

Phased array inspection using bolt scanner enables hard copy output and easy-to-interpret imaging. It also provides the ability to monitor component condition. It can be applied to bolts, studs, bridge pins and other similar applications. For a quick review of bolt condition, upon completion of the scan, the operator can move through the scan data. This data is digitally stored enabling periodic monitoring and options for post-analysis or remote analysis.

Key Benefits of our PAUT solution for Bolt Inspection :

- Inspection can be performed without removing the bolt or stud, meaning that there is no downtime or need to decommission the structure involved.

- Allows for corrosion and crack detection on components such as bolts, bridge pins or studs.

- Easy-to-interpret imaging of thread loss or damage to pin or shaft surface.

- For accurate defect sizing, our encoded scanner allows for consistent and repeatable inspection.

- All data is digitally stored for post-analysis and monitorization of known defects.

- Our standard scanner solution consists of 3 distinct clamp hubs, each marked with the maximum width of the bolt head or nut.

- Special housings can be made on demand when working with bolt sizes outside of the standard range.
