|Sound waves determine weld soundness
Traditional ultrasonic systems use piezoelectric transducers to generate sounds waves and a couplant—a liquid—to provide a pathway for the sound waves to pass from the transducer to the material under test. An electromagnetic acoustic transducer is an alternative technology, one that uses two electromagnets to generate the sound wave in the part to be inspected. This eliminates the couplant, which can interfere with the test process.
