Abstract:

Gas Metal Arc Welding (GMAW) is an arc welding process to join two or more metal materials through fusion, where an electric arc is formed between a consumable electrode and the base metal. It has been reported that expert GMAW welders are able to maintain and direct the welding arc based on the welding sound, and psychoacoustic experiments showed that the welding performance significantly degraded without the acoustic feedback to the professional welders. However, the mechanics of sound production in the GMAW process has not been understood well. In this paper, a multi-sensor system is established to measure the welding sound simultaneously with multiple physical welding parameters to investigate the generation mechanism of welding sound. An acoustic model is proposed to predict the welding sound signal from the physical welding parameters. The current work enhances the understanding of the welding sound production mechanism.
