A welding machine requires three additional basic components for truly automated operation: sensors which detect physical properties of the weld; a model of the welding process which relates the controllable welding parameters, current, voltage, welding speed, etc., to the physical properties of the weld; and a control system which takes the signals from the sensors and converts them into a form which can be used for feedback control of the welding machine. As part of a larger program to investigate all aspects of this problem, this study is concerned with the development of ultrasonic sensors to detect the physical properties of the weld. 14 refs., 5 figs.
