Acoustic Emission Diagnostics of Welding Process for Technical Sea Objects

V. A. Gumenuk, N. A. Kazakov, V. A. Sulzhenko

The paper considers examples illustrating application of a multi-parameter system for classification of AE sources hazard as factors of potential defects based on an integrated broad-band signal parameter incorporating the peak amplitudes, wave form characteristics and spectral power. The efficiency of the multi-parameter analysis concept is demonstrated for one of the most complicated cases – on-line AE diagnostics of the welded joints directly during the welding process.
