The invention relates to a method for nondestructive testing of a metallic workpiece () using an ultrasonic transducer testing head having the following steps: to generate an ultrasonic wave, an excitation pulse is transmitted using the ultrasonic transducer () to the workpiece (), a response signal is measured using the magnetic field sensor (), testing information, preferably transit time information of the ultrasonic wave and therefrom wall thickness information about the thickness of the workpiece (), is ascertained on the basis of an ultrasonic echo component of the response signal, and further information, in particular distance information about the distance of the testing head from the workpiece (), is ascertained on the basis of a magnetic field component of the response signal by supplementary analysis. The invention also relates to a corresponding analysis method for analyzing measurement data which has been ascertained using an ultrasonic transducer testing head and a system for nondestructive testing of a metallic workpiece.
