ULTRASONIC WELD JOINT STUDY

THE USE OF ULTRASONIC TESTING FOR INSURING QUALITY BUTT WELDED JOINTS IS DISCUSSED. THE ASSURANCE OF THE QUALITY OF BUTT WELDED JOINTS IS PRESENTLY OBTAINED BY RADIOGRAPHIC INSPECTION ON ALL CALIFORNIA DIVISION OF HIGHWAYS FABRICATED STEEL STRUCTURES AS SPECIFIED IN TEST METHOD NO. CALIFORNIA 601-F. AN APPRECIABLE ECONOMIC SAVINGS COULD BE REALIZED BY SUBSTITUTING ULTRASONIC INSPECTION IN PLACE OF RADIOGRAPHIC INSPECTION. THERE ARE, HOWEVER, MANY DIFFICULTIES PRESENTLY CONFRONTING THE ULTRASONIC OPERATOR THAT, TO DATE, HAVE NO SOLUTIONS. PROBLEMS DEALING WITH SCANNING INTERPRETATION WHEN (1) WELDS ARE UNGROUND, (2) BASE METAL PLATE IS LAMINATED, AND (3) DEFECT LENGTHS ARE TO BE ACCURATELY DETERMINED, ARE JUST A FEW. CONTINUED RESEARCH ORIENTED TOWARD RESOLVING THESE PROBLEMS IS MANDATORY BEFORE ULTRASONIC INSPECTION CAN BE RECOGNIZED AND FULLY ACCEPTED AS ASSURING QUALITY BUTT WELDED JOINTS. /AUTHOR/
