ULTRASONIC INSPECTION OF BUTT WELDS IN HIGHWAY BRIDGES

THE USE OF ULTRASONICS TO REVEAL DETRIMENTAL WELD FLAWS IN FINISHED BUTT WELDS IS DISCUSSED. THE OBJECTIVE WAS TO DETERMINE IF ULTRASONIC INSPECTION COULD BE USED TO REVEAL SERIOUS FULL PENETRATION BUTT WELD DEFECTS THAT MAY DEVELOP IN THE FABRICATION OF STRUCTURAL STEEL BRIDGE GIRDERS. CONVENTIONAL WELD INSPECTION HAS RELIED HEAVILY ON RADIOGRAPHY. THE INHERENT SAFETY PROBLEMS ASSOCIATED WITH RADIOGRAPHIC EXAMINATION, TOGETHER WITH ITS OTHER LIMITATIONS, HAS AROUSED SUBSTANIAL INTEREST IN ULTRASONICS AS A MEANS OF FLAW DETECTION. PROBLEMS AREAS SUCH AS OPERATOR TRAINING, REPEAT ABILITY OF FINDINGS, AND INTERPRETATION AND DOCUMENTATION OF FINDINGS ARE INVESTIGATED THROUGH BOTH LABORATORY AND IN-SERVICE STRUCTURAL APPLICATIONS. /FHWA/
