Abstract

The measuring proceeds simultaneously on two, identically long tracks in the direction of material width, which are delimited on both sides by pairs of piezoelectric sensors, dividing the plate material onto two halves. The length of each measuring track is equal to the half of the plate material width, reduced by shift of the sensors from the edge and the longitudinal axis of the plate material where the sound pulse generator is operating. On the basis of the measurement results it is possible to evaluate hardness quality or presence of an internal defect.
