Abstract

A modified tabular method for locating acoustic-emission signals, which is intended for determining the coordinates of flaws when inspecting a multiple-run welding process with a lower error rate, and the result of using this method for determining the coordinates of flaws when welding a circular contour using a piezoelectric antenna, which consists of four acoustic-emission transducers, are considered. It is shown experimentally that the application of the modified tabular method allowed an increase in the accuracy of determining the coordinates of introduced flaws when using the acoustic-emission testing method.
