Abstract Abstract： This paper developed a passive visual sensing technology with doublewindows inspection, which was applied in gas tungsten arc welding (GTAW) for aluminum alloy. The profile of pool and seam gap was measured clearly. These data were applied in the weld quality control and seam tracking, and the sensor was used in component welding in the rocket.
