英文摘要: Cable-type welding wire (CWW) electrogas welding (EGW) is an innovative process in which CWW is used as the consumable electrode. Seven wires can be melted simultaneously with only one welding power source, one wire feeder, and one welding torch. This paper reports a study of the sidewall penetration of CWW EGW. The results showed that all the mechanical properties of CWW EGW welded joints met the standards of the China Classification Society (CCS). The arc heating area of CWW EGW was large and that the unique rotating arc of CWW EGW had a strong stirring effect, enhancing convective motion of the molten pool and accelerating heat transfer between the superheated molten pool and the sidewall. The droplet of the CWW EGW appeared to be non-axial transfer due to the rotating force. The...
