ABSTRACT:
An optoelectronic detection system is disclosed for real time checking or inspection of a total penetration weld suitable for a joint which cannot be directly observed. The system involves an optoelectronic detector and an optical fiber with one end of the fiber being positioned so that it faces the detector and the other end collects the light intensity at the back of the welding bead. The end which collects the light intensity is cut into the shape of a cone and the optical fiber may be protected by a sheath made from a ductile material.
