WELDING DEFECTS FROM STEREORADIOGRAPHS

A STUDY WAS CONDUCTED TO IMPROVE NON-DESTRUCTIVE TESTING TECHNIQUES FOR DETECTING AND CHARACTERIZING FLAWS IN HIGH-STRENGTH WELDED STEEL JOINTS. IT WAS CONSIDERED NECESSARY TO DETERMINE THE SIZE AND DEPTH OF THESE FLAWS. THREE TECHNIQUES WERE CONSIDERED: RADIOGRAPHY, STEREORADIOGRAPHY AND ULTRASONICS. STEREORADIOGRAPHIC MEASUREMENTS BY PHOTOGRAMMETRIC METHODS OFFERED THE BEST SOLUTION FOR THESE INVESTIGATIONS. THE STERORADIOGRAPHS WERE TAKEN AT DIFFERENT FOCUSFILM DISTANCES, APPLYING DIFFERENT TUBE SHIFTS TO ASCERTAIN THE BEST FOCUS-FILM TO TUBE- SHIFT RATIO. USING PARALLAX MEASUREMENTS, THE DEPTHS OF THE DEFECTS WERE DETERMINED, AS WELL AS THE ACCURACY OF THE MEASUREMENTS. /AUTHOR/
