ABSTRACT:
A system and method for monitoring the operating condition of an electrode dresser for an automated spot welder includes a sensor for sensing an operating characteristic of the dresser. The output produced by the sensor is analyzed by a data acquisition system to determine the operating condition of the dresser. Various types of sensors may be employed including a current sensor which senses current flowing through the dresser motor, a flux sensor which senses leakage flux produced by the dresser motor, and a vibration sensor which senses vibration produced during operation of the dresser. Operating characteristics determined by the data acquisition system include whether the electrode dresser is operational, whether the dresser has been engaged by the electrodes of the welder, the amount of time that the welder electrodes were in dress, and the quality of the dress. The data acquisition system may also be configured to perform spectral analysis of sensor data to determine the presence of anomalous dresser operating conditions.
