Abstract

The invention relates to a process for testing the generative production of a component, the process comprising the following steps: at least one ultrasonic transducer device having a transmitter device for emitting ultrasonic signals is provided; at least one receiver device for receiving ultrasonic signals and determining at least one parameter of the ultrasonic signals is provided; an evaluation device for evaluating the at least one parameter is provided; at least one powder layer consisting of a powder which can be solidified by energy radiation is applied to a building platform and a selected region of the powder layer is solidified by energy radiation to form a component region; at least one partial region of the solidified component region is acted upon by ultrasonic signals by means of the transmitter device; the reflected ultrasonic signals are received; at least one parameter of the reflected ultrasonic signals is determined; and the at least one parameter is evaluated by the evaluation device.
