Welding sound benchmark data

Benchmark data for gas metal arc welding sounds at different modes. The overall aim of this project is to develop an acoustic sensing based monitoring technology for process and quality control and productivity enhancement of Gas Metal Arc Welding (GMAW). The specific aims are to:  establish an acoustic model that correlates the acoustic signal with other weld parameters by investigating the physical mechanisms of GMAW sound generation;  determine key acoustic features and identification algorithms for GMAW process monitoring by establishing and analysing the database of multimodal weld recordings;  develop a prototype GMAW process monitoring system based on the acoustic model established in the project and the key acoustic features identified in the project.
