The development of a defect-rejection procedure for multiple-pass welding by the distribution of the principal parameters of acoustic-emission signals
Source abstract
Abstract
During quality control of welding, rejection levels were determined using the comparison of the distribution of the parameters of acoustic-emission (AE) signals with introduced defects represented by titanium and tungsten inserts. The MARSE energy parameter, the mean number of oscillation along the leading edge of an AE signal, and the two-interval coefficient were used as the principal informative parameters that are most sensitive to welding defects. The Student-t and Kolmogorov-Smirnov criteria with the calculation of rejection levels and their localization allow the location of defects in the course of multiple-pass welding.
