| Outline of Final Research Achievements |
An acoustic emission (AE) measurement system which includes a novel waveform analysis method with parallel processing by GPGPU was developed for monitoring of materials working processes under noisy environment. Herewith, parameter settings are no longer needed for noise reduction and AE event detection. The whole analysis is done in real time and automatically.
Furthermore, friction stir welding (FSW) and suspension plasma spraying (SPS) processes were monitored by the developed AE measurement system. Defects were detected in real-time and the effectiveness of process controlling which is based on this result was shown.
