Abstract
In this article, to improve the stability of droplet transfer and reduce the spatter of pure carbon dioxide gas shield welding (CO2 welding), we propose a new welding method called EMS-CO2 welding by applying an additional longitudinal electromagnetic field to a CO2 welding process (abbr. EMS-CO2 welding). The characteristics of droplet transfer, welding formation and microstructure between EMS-CO2 welding and general CO2 welding on a Q235 low carbon steel plate are studied. The results show that EMS-CO2 welding improves droplet transfer process, increases the stability of droplet transfer, and delivers better control of the welding spatter. Meanwhile, EMS-CO2 welding generates welding formation with refined grains, welding seams with uniform microstructure, and welding joints with a higher quality. Therefore, EMS-CO2 welding stands for the state of the art in short-circuit transfer CO2 welding especially.
