ABSTRACT:
A system for monitoring and controlling a welding/brazing operation on a workpiece having two spaced apart materials with a brazing material disposed therebetween. The system includes a welding apparatus having two spaced apart electrodes. A current is applied through the electrodes and the workpiece sufficient to melt the brazing material. A controller controls the brazing operation by controlling the duration of time during which current flows through the workpiece. A non-contact sensor is coupled to the controller and measures the temperature of the brazing material, so that upon a predetermined temperature measured by the sensor, the controller causes the termination of the current to the workpiece.
