SYSTEM AND METHOD FOR MONITORING WELD OPERATION

摘要

PROBLEM TO BE SOLVED: To provide a system (10) for monitoring a weld operation. SOLUTION: The system includes an ultrasonic wave generator (28) adapted to deliver an ultrasonic wave to a target material (12) during the weld operation, and an ultrasonic receiver (30) adapted to receive the ultrasonic wave propagated through the target material (12). The system (10) also includes a signal processor (36) adapted to determine a quality level of a weld created during the weld operation by extracting data corresponding to a torsional mode from the ultrasonic wave and comparing the data to a profile that corresponds to an acceptable quality level.
