Sensitivity of a flaw detector during ultrasonic testing by chord-type transducers
Source abstract
Abstract
During testing of girth-welded joints by chord-type transducers, it is suggested that the sensitivity of a flaw detector additionally be tuned by using a corner reflector (notch); the corresponding structure of transducers and specimens is presented. Additional tuning by a notch makes it possible to detect and estimate root discontinuities (on the bottom surface of a welded joint) and simultaneously to exclude the interfering echo pulse caused by a sag (the lower reinforcing bead) of the welded joint.
