Temperature Simulation of Aluminium Alloy Double-Arc Welding Process on Simplified Conditions

Abstract:

In this paper we used ANSYS finite element software to simulate the temperature field in 7a52 aluminum alloy double-arc welding process and analyze the welding seam's forming characteristics. We conducted the welding temperature field numerical simulation in the same welding seam forming conditions by loading heat source of single-arc and double-arc separately, which used gauss heat source model and used voltage, welding current and speed as key parameters. The experiments indicated that the designed double-arc heat source model could generally represent the double-arc welding process. Compared with single-arc welding process, the double-arc welding had higher welding efficiency and narrower heat affected zone. Furthermore, the temperature of double-arc welding pool raised faster. All these advantages could improve the welding efficiency.
