Abstract
A method, a computer program and a system for ultrasonic inspecting of objects is provided. The method comprises positioning () a measuring device () comprising a plurality of transducers () on the inspected object () and performing a number of test signal acquisitions (). Each acquisition includes using one transducer to induce an ultrasonic signal into the test object, and using at least one other transducer to receive an ultrasonic test signal. The inspecting further comprises determining () the influence of contact surface variations between each test signal and a reference signal; compensating () the full test signal for the contact surface variations; and determining () a residual signal. The system comprises a computing device (), and a measuring system () communicatively connected to the computing device (). The measuring system () includes an ultrasound unit () and a measuring device () provided with a plurality of transducers (). The computing device () comprises a calibrator () to determine () the influence of contact surface variations, and compensate () the test signal. The computing device () comprises a residual calculator () to determine () the residual signal.
