Identification of Acoustic Emission Signatures of Direct Laser Melting Process
摘要
Abstract
The paper discusses identification of acoustic emission signatures of processes occurring during direct laser melting. As part of the experimental study, samples from the powder alloy Inconel 648 were grown in various modes with simultaneous recording of acoustic emission signals. Based on the analysis of registered signals parameters, we recorded their characteristic distribution patterns during laser melting of defect-free and defective samples.
