ABSTRACT:
An gas metal arc welding (GMAW) process is monitored by disposing a light intensity sensor in the vicinity of the arc, such that the output signal from the sensor is responsive to the intensity of the arc. The arc light intensity is analyzed to determine the arc length, and to determine of the mode of metal transfer and whether the welding process is proceeding as intended.
