Abstract
In order to safely interfering signals caused by interfering volumina like e.g. air bubbles existing in a coupling medium from signals generated by workpiece defects in the ultrasonic testing of workpieces according to the pulse-echo-method, it is suggested that at the appearance of a signal in the time between transmitting pulse and surface echo-signal crossing an adjustable threshold during a test cycle, all signals of the same test cycle falling within the range of anticipation for workpiece defects will be suppressed.
