A computer-based gas tungsten arc welding (GTAW) system, developed at Mid-South Engineering, Inc. and Vanderbilt University under contract to the National Aeronautics and Space Administration (NASA), is described. Emphasis is placed on the process modeling and digital feedback control loops. The system is shown to be capable of accepting user inputs in terms of desired output features, comparing these to actual sensed output features (or features estimated by real-time process modeling), and producing the required compensatory adjustment in the equipment parameters.
