Probe for ultrasonic flaw detectors
TLDR
In this article, a probe for ultrasonic flaw detectors includes a transducer and either a protection plate to protect the transducers or a metallic part for attaching them directly to the object to be tested for flaws.Abstract:
A probe for ultrasonic flaw detectors includes a transducer and either a protection plate to protect the transducer or a metallic part for attaching the transducer directly to the object to be tested for flaws, these two parts being bonded to each other with a heat-resisting brazing or soldering material. Because of its high bonding strength, the probe thus formed is not only capable of serving both in high and low temperature ranges, but also may be used in a roving mode or in a stationary mode in testing the object.read more
