A high effective non-consumable double electrode GMAW (Gas Metal Arc Welding) method is presented. A dynamic mathematics model for decoupling welding arc was developed adopting the method of equivalent current path according to the arc dynamic characteristics of non-consumable DE-GMAW process. Then the process of non-consumable DE-GMAW process was simulated and analyzed by MATLAB/Simulink. The results show that the developed mathematics model can reflect the DE-GMAW process well, and higher efficiency than conventional GMAW and lower spatter can also be ensured.
