Embodiments include an electromagnetic acoustic transducer (EMAT) system. The EMAT system includes a plurality of magnets and a conductor set. The plurality of magnets has a like pole arrangement and wherein each magnet is in close proximity to one another. The conductor set includes electrically conductive elements. A portion of the conductor set is positioned proximate to the plurality of magnets. The plurality of magnets and the conductor set are positioned proximate to a test object. The EMAT system is configured to perform at least one of generating and receiving an elastic wave. Embodiments also include a method of elastic wave measurement for nondestructive testing and evaluation. The method includes the steps of positioning an EMAT proximate a test object, generating an elastic wave such that the elastic wave propagates about the test object, detecting the elastic wave propagating about the test object, and analyzing difference in elastic wave character between the elastic wave in the generating step and the elastic wave in the detecting step to evaluate the test object.

Systems and methods for generating ultrasonic waves, exciting special classes of ultrasonic transducers and ultrasonic devices for engineering measurements

Systems, devices, and methods of inspecting a body of a tubular, are provided. An exemplary electro-magnetic acoustic transducers (EMAT) tubular inspection system for inspecting a body of a tubular includes an EMAT in-line tubular inspection device. The device can include a spine having a longitudinal support body and radially projecting rails, and multiple telescoping sections each connected to the radially projecting rails. The telescoping sections can include a magnetic back panel, one or more wheels positioned to engage an inner surface of a body of a tubular during inspection, and signal propagating and receiving modules carried by the magnetic back panel. Each module can include a magnet and different types of EMAT inspection transducer coil arrangements connected to the magnet. The different types of EMAT inspection transducer coil arrangements provide for the generation of NBSH, SW, and SV waves.
