    Abstract: Based on the features of double electrode gas metal arc welding (DEGMAW), a new hybrid heatsource model for DEGMAW was proposed. Using this heatsource model, the temperature fields of DEGMAW with different welding parameters were simulated. According to the simulation results with different welding parameters, the influence of welding parameters to the heat input to base metal in DEGMAW were analyzed. To verify the rationality of the hybrid heatsource model of DEGMAW, the simulation results of the temperature field were compared with the experimental results with same welding parameters. The research results indicate that under the same total current, the heat input to base metal decrease gradually with the increase of bypass current. In addition, the closer to the welding line from the measured point the greater decrease rate of the heat input to base metal. By the study and comparison of the thermal cycle curve of measured points, the simulation results were in good agreement with the experimental results. These results indicate that the calculated temperature field is accurate and the hybrid heatsource model is rational.
