AE signals as laser cutting quality indicators

The paper presents results of an analysis of acoustic emission (AE) signals obtained during laser cutting of a steel plate, which is frequently used in the production of automotive body components. The acoustic emission in the plate, which is produced by various physical phenomena occurring during the laser cutting process, was measured with contact PZT sensors. During the laser cutting process...
