비전센서를 이용한 머플러 TWB 레이저 용접에서의 실시간 용접선 추적 및 품질검사 연구

This research was conducted as a fundamental study to apply tailor welded blank technique into automotive production process. Specially we tried to apply the TWB technique to exhaust system. Seam tracking and inline monitoring method using laser vision sensor were studied in this paper. Seam tracking process has to be operate at the same time with laser welding because it performs the function of correcting the beam path error prior to shooting the laser beam. On the other hand, in case of quality monitoring, it is the most important to define the defects on laser butt welding process. Therefore, in In this study, we were selected the suitable system for performing the seam tracking and quality monitoring by defined functions. After the verification of the performance was carried out through a basic experiment for the selected system.
