Abstract
The utility model relates to a special test block for ultrasonic flaw detection, which belongs to the technical field of the ultrasonic flaw detection. The special test block has a columnar body, andhas a double-arc cross section consisting of two superposed double-semicircular arc surfaces with the same diameter. A standard reflector formed of two coaxial holes is arranged on the columnar body;and the hole axis is parallel to the central line of the columnar body. The center of the standard reflector formed by the two coaxial holes passes through the common cord of the two arcs, and passesthrough the right-angle vertex of a right-angled triangle including the connection line between two circle centers of the two arcs as the bevel edge. The two coaxial holes are flat-bottomed holes. Thespecial test block can solve the problem in measuring parameters of a curved ultrasonic angle beam probe, such as the front-edge size, the K value and the resolution, during ultrasonic detection of longitudinal cracks on the inner wall of the middle and small-diameter pipes or elbows. The special block has the advantages of simple and practical test method, good portability, and is mainly used for parameters measurement of the curved ultrasonic angle beam probe.
