Optimization of Parameters of Electromagnetic-Acoustic Thickness Gauges for Thin-Wall Structures
Source abstract
Abstract
Operation of ultrasonic thickness gauges with electromagnetic-acoustic (EMA) detection and excitation has been studied. The mode of operation using testing signals in the form of trains of two to four acoustic shear oscillations is preferable to the impact excitation in tests of thin-wall pieces (pipes, sheets, T-bars, etc.). The carrier frequency can be up to 8 MHz. The results of the reported study have been used in designing EMA thickness gauges for pipes.
