Abstract
The state of fusion is one of the primary determinants of weld quality. Because the fusion state is specified by the top-side and back-side widths of the weld pool, a direct feedback measurement of the fusion state requires both top-side and back-side sensors. However, it is often difficult for a sensor to access the back-side of certain constructions, and a back-side sensor cannot be attached to and moved with the torch. A neurofuzzy system was developed to precisely estimate the back-side bead width using the measured top-side geometry of the weld pool. The feedback could, therefore, be used for the closed-loop control of the fusion state. A closed-loop control system was designed to regulate the welding process to achieve the desired fusion state.
