Abstract: The tandem welding process establishes a means for increasing both the travel speed and deposition rate. Electromagnetic force models of the tandem weld pool are developed. Thermal fields and flow fields under tandem heat sources are simulated. Simulation results show that flow characteristics of the weld puddle are affected by source process parameters.
