The main idea is to develop a set of signal processing methods (SPMs) to provide fast data acquisition and to ensure the reliability and security of energy systems. The Lamb waves can efficiently interact with defects and detect damages that are not visible from the outside. The location and size of defects can be determined by changes in phase and group velocities obtained in the defect and non-defect regions. However, interpreting the received signals and obtaining the required data is a challenging task due to the complexity of the signals, the unusual nature of wave propagation, infinite number of dispersive An and Sn modes, etc. Thus, the acquisition of Lamb wave signals at many points along the wave propagation path must be performed, but this is time-consuming and laborious. A novel set of methods must be developed, that would provide data avoiding the object scan, thus saving time and effort. The verification and accuracy assessment of the SPMs according to the requirements of ISO 17025 and ISO 9712 would be performed within the Nondestructive Tresting (NDT) community
