Design & Development of 4-channel Phased Array Control & Amplifier for EMAT based Phased Array UT System for Weld Joints

Abstract

Weld joints in Austenitic steel are very difficult to inspect using conventional UT technique employing piezoelectric transducers. EMAT (Electro Magnetic Acoustic Transducer) based UT technique is more suited for such applications by generating Shear Horizontal (SH) wave mode. Due to lower efficiency of EMAT, ultrasound is focused using multiple elements… (More)
