1. A laser hybrid welding system, comprising: a welder configured to perform a laser hybrid welding operation in which a workpiece is heated by a laser and filler metal is added by an arc welding process; a sensor configured to acquire data regarding a parameter of the laser hybrid welding operation; and a controller communicatively coupled to the sensor and configured to receive the acquired data from the sensor, to determine whether the acquired data is indicative of a welding defect, and if the acquired data is indicative of a welding defect, to output a control signal that directs the laser hybrid welding system to attempt to fix the welding defect.
