THREE-DIMENSIONAL MATRIX PHASED ARRAY SPOT WELD INSPECTION SYSTEM
摘要
A system for characterizing a spot weld including an acoustic probe that further includes a plurality of ultrasonic transducer elements arranged in a curved array, wherein the transducer elements are operative to generate ultrasonic signals and to receive reflections thereof; and a combination of materials for allowing the probe to conform to a contoured surface of the spot weld while enabling sound energy to be transferred directly into the spot weld under test conditions; a phased array excitation unit coupled to the array of transducer elements for ultrasonically exciting transducer elements; and a controller coupled to the phased array excitation unit for controlling the operation of the phased array unit, gathering and processing information from the ultrasonic transducers, and generating a two-dimensional, color coded image that characterizes the integrity of the spot weld.
