Abstract

In this method, particularly in the testing of rolling-mill sections for surface defects, the locally existing defect signals are amplified with respect to the statistically distributed noise signals by adding them together line by line. For this purpose, N lines are added together and the aggregate signal is analysed. Pattern recognition is also possible in this arrangement.
