ABSTRACT:
An improved optical portion of a vision system for controlling an automated arc welding system. Collimated, image bearing light is rotated through an angle to maintain the weld scene at the identical orientation upon the video camera regardless of actual orientation changes during welding operation. An iris reduces the light intensity to maintain the light which is incident upon the video camera from the more intense weld pool region, within the range of the camera while light from the joint region is integrated over multiple frames so that good resolution is also obtained for the image of the joint region.
