Paper presents utilized innovative setup for eddy current tomography and possibility of its utilization in automotive industry. Described tomography setup is designed for testing axisymmetric objects thus motor valve was selected for exemplary testing. Tests were conducted on motor valve in original state. Afterwards reference defect was created on element and measurements were repeated. Significant difference between tests results were observed, thus potential for utilization in automotive industry was confirmed. Finite element method simulations were applied in order to confirm the measurement results. Calculations were conducted in open-source finite element method software, which solves Maxwell equations in the A-V form. Modelling results confirm possibility of finite element method-based inverse tomography transformation.
