This paper presents a newly developed electromagnetic acoustic transducers (EMAT) probe with eight transmitter
and eight receiver segments aiming to improve performance of a phased array EMAT probe with four transmitter and
four receiver segments. Results of tests on artificial flaws in HAZ in a 6 inch diameter austenitic mock-up pipe were
shown for characterizing its performance. The UT result with a conventional Piezo transducer was also referred for
