A novel and highly effective double-electrode metal inert gas (MIG) welding process was presented. However, the coupled arc under open-loop control condition was unstable, which led to serious defects in the resultant weld. A closed-loop control system for double-electrode MIG welding process was designed to resolve the instability problem under open-loop control system. Then a rapid prototyping control system based on xPC real-time target technology was established, and the control software was designed with Matlab/Simulink tools. The results show that the fuzzy controller can satisfy the arc stabilizing control requirement, and have higher efficiency and lower spatter than the conventional MIG welding process.
