IMPROVED COUPLING MEDIUM SUPPLY OF AN ULTRASONIC TEST DEVICE

摘要

An ultrasonic testing method is provided. The ultrasonic method includes non-destructively testing a test object with an ultrasound generated by an ultrasound probe, continuously circulating a liquid coupling medium outside of the test probe before and/or during non-destructively testing the test object, branching a part of the liquid coupling medium off from the circulation, and feeding the branched liquid coupling medium to a coupling chamber arranged between the ultrasound probe and the test object.
