Testing of problem-adapted test probes on test pieces

Creators

Description

The piezoelectric transmitting-receiving angular test probes, in which the concept of multilayer adaptation is used for adjusting the bandwidth of the ultrasonic pulses, were tested systematically for their efficiency in longitudinal and transverse defect detection. The results were to show what welding conditions cause 'blind' zones in austenitic welds, and how the results can be improved. (orig.)

Abstract (German)

Ziel dieses Vorhabens ist es, die piezoelektrischen Sende/Empfangs-Longitudinalwellen-Winkelpruefkoepfe, bei denen das Konzept der Mehrschichtanpassung zur Einstellung der Bandbreite der Ultraschallimpulse verwendet wird, systematisch bei der Laengs- und bei der Querfehlerpruefung zu erproben, um aufzudecken, unter welchen Pruefbedingungen 'blinde' Zonen bei austenitischen Schweissverbindungen zu verzeichnen sind und wie solche Pruefbefunde zu verbessern sind.
