• Electrolytic aluminum
• Motion control
• Multi-layer and multi-pass automatic welding
• Welding robot

Aiming at the special environment of aluminium plant,a welding robot system composed of mobile platform,manipulator arm and welding device was developed with the control system as the core. The motion control system of the robot was composed of lower computer and upper computer: the lower computer adopts motion controller MC464 in real time to control servo motors; and the upper computer adopts tablet computer for human-machine interface, and also the camera data were acquired communicating with welding machine and control box. This robot could work in two modes(teaching and playing). The results show that the robot system is able to accomplish multi-layer and multi-pass automatic welding of steel cathode to the explosion welding steel plate in the aluminum electrolytic cells. Voltage drop in the busbar connection can greatly be reduced, which can not only conserve energy and reduce consumption, but also improve the life of electrolyzer by ensuing uniform electrolytic cell current.
