Zusammenfassung:	A method (100) of nondestructive testing of a joint (16) between an electrical terminal (12) and a wire cable (10) that is bonded to the electrical terminal (12) is presented herein. This method (100) includes the steps of providing an ultrasonic transducer (18) in electrical communication with an electrical signal generator (20) and signal analyzer, placing the transducer (18) in ultrasonic communication with the joint (16), transmitting a first ultrasonic signal (22) via stimulation of the transducer (18) by a first electrical signal having a first frequency from the signal generator (20), receiving a first reflected signal (26) of the first ultrasonic signal (22) via the ultrasonic transducer (18), transmitting a second ultrasonic signal (28) via stimulation of the transducer (18) by a second electrical signal having a second frequency different than the first frequency from the signal generator (20), receiving a second reflected signal (30) of the second ultrasonic signal (28) via the transducer (18), and determining the quality of the joint (16) by analyzing the first and second reflected signals (26, 30).
