Abstract: A method of assessing bolted joint integrity. A guided wave is sent through a structure containing at least one bolted joint. The guided wave that is subsequently propagated through the structure and interacted with the bolted joint is measured to obtain a measured result.

An incorrect torque level of the bolted joint is inferred from any changes that are determined.
