1. A system for assessing the quality of a spot-weld joint between pieces of metal, the system comprising:

  • an ultrasound transducer for probing a spot-weld joint, the ultrasound transducer transmitting ultrasonic radiation into the spot-weld joint, receiving corresponding echoes, and transforming the echoes into electrical signals;

    an image reconstructor connected to the ultrasound transducer for transforming the electrical signals into numerical data representing an ultrasound image;

    a neural network connected to the image reconstructor for analyzing the numerical data; and

    an output system for outputting information representing the quality of the spot weld joint.
