TL;DR: Weld arc voltage, weld arc current and weld arc travel speed are monitored on a real-time basis during the welding process in this paper, and an alarm is activated when a preselected variation in the measured and the reference quantities occurs.
Abstract: Weld arc voltage, weld arc current and weld arc travel speed are monitoredn a real-time basis during the welding process. Each monitored quantity or parameter is compared directly with a reference value indicative of a high quality weld, and an alarm is activated when a preselected variation in the measured and the reference quantities occurs. The monitored quantities are also used to calculate additional welding parameters, including heat input, weld bead area and cooling rate. These parameters are also compared to ideal reference values in order to control weld quality. The sensors used for measuring the welding parameters are selected so as to provide minimal interference with the welding process. For example, Hall effect transductors are used for current measurements, while a unique opto-electronic noncontacting sensor is used for measuring the weld speed.
