WELDING TORCH WITH VISION ATTACHMENT Abstract of the Disclosure A gas tungsten arc welding torch suitable for robotic welding has an improved built-in optical vision sensor which images the weld puddle and weld region on the face of a fiber optic cable; the image is relayed to a video camera and computer to control the torch motion and weld process. The electric are is much brighter than the area around the arc it is desired to image. A shaped blocking device on the tungsten electrode, such as a molybdenum sleeve or collet set back so that the arc is undisturbed, prevents the arc from being imaged and eliminates image distortions caused by the presence of the bright arc.
