Ultrasonic method and apparatus for spot weld control
TL;DR: In this paper, a pair of opposed spot welding tips transmit and receive ultrasonic waves and associated circuitry measures the time of flight between the transducers which is a function of tip separation, workpiece temperature and nugget size which are indicators of the progress of a weld.

Method and apparatus for spot weld control
TL;DR: In this article, a pair of opposed spot welding tips (24) transmit and receive ultrasonic waves and associated circuitry (16,18) measures the time of flight between the transducers which is a function of tip separation, workpiece temperature and weld nugget size which are indicators of the progress of a weld.
