Abstract
A robotic welding system has a remote light pattern generator and a remotely located video camera and controller connected to an arc welding torch by flexible coherent fiber optic bundles. The improved torch has integral projection and viewing optical systems supported on the ring-shaped torch body. The first projects the light pattern onto the workpiece to measure workpiece profile and detect the joint location; the second produces an image of the weld puddle and light pattern for use as feedback information. The optical systems are tilted away from one another at a small angle corresponding to the angle of reflection to provide for optimum interception of the projected light pattern by the viewing optics.
