ABSTRACT:
An ultrasonic test head for ultrasonically testing flaws in a workpiece includes a common housing. An ultrasonic transducer configuration is disposed in the common housing. At least one ultrasonic transducer array is disposed in the common housing for operation in a pulse echo mode for transverse waves propagating in a workpiece. The ultrasonic transducer configuration includes at least two acoustically separate ultrasonic transducers to be operated in a transmit/receive mode for longitudinal waves propagating near a surface in the workpiece. In a method for operating the ultrasonic test head, each ultrasonic transducer array or arrays is operated in a transmit/receive mode.
