Nondestructive test (NDT) technology is required in the gas metal arc (GMA) welding process to secure weld robustness and to monitor the welding quality in real-time. In this study. a laser vision sensor (LVS) is designed and fabricated. and an image processing algorithm is developed and implemented to extract precise laser lines on tested welds. https://www.roneverhart.com/Eugenia-Spiral-Topiary/
