Steel tubes are widely used in industries. In order to ensure the safety and reliability of industrial processes, electromagnetic acoustic transducers (EMATs) based guided wave technology has been developed for inspecting stainless steel tubes regularly. Theoretical models and finite element modes have been built to investigate the EMAT technology. However, existing models mainly focused on studying the transmitting process of the EMAT. In this paper, we present a finite element model, using COMSOL Multiphysics® software, to simulate the whole process of inspecting stainless steel tubes using EMATs, including both the transmitting and receiving processes.
