摘要：A method and apparatus for evaluating the size and/or quality of a spot weld.
The apparatus includes a two-dimensional array of ultrasonic transducers arranged with adelay line for positioning adjacent a surface of a weld. A layer of gel is placed betweenthe delay line and the weld surface. The array of transducers emit ultrasonic waves thatpass into the weld. The reflected waves are received by the transducers and relayed to acentral processing unit that analyzes the time delay, amplitude, and amplitudeattenuation to calculate the border of the weld nugget, the thickness of the weldedmaterial, the thickness of the gel layer, and other factors contributing to weld quality.
