This paper studies a new robotic double sided arc automatic welding system for middle-thick aluminium alloy plates, designs its scheme and synchronous communication circuit. This system consists of robot, digital welding machine and positioner, which are made up into a robotic double sided arc automatic synchronous vertical welding working cell. The welding experiment result shows that the system can be used to realize the robotic double-sided TIG arc synchronous automatic welding process, thus greatly improving the automation welding efficiency. The experiment results also show that the automatic welding system has advantages of short welding cycle, stable weld- ing process, it is a promising and high efficient welding equipment in the welding field for the medium and heavy plates.
