Abstract
A spot-welding electrode assembly includes an electrode, an electrode cap at an outer end of the electrode, and a plurality of transducer elements positioned inward of the electrode cap. The transducer elements may be micro-elements. A method for monitoring a weld formed by a spot-welder includes passing current from an electrode assembly through a stack-up, transmitting an ultrasonic wave from each of a plurality of sources in the electrode assembly to a plurality of points in the stack-up, and monitoring the ultrasonic waves to monitor the weld formation.
