Abstract: Since there are many adjustable parameters in alternative speed wire-feeding pulsed submerged-arc welding process,selection of pulsed parameters on the basis of the simulating model was investigated in this paper.The impact of pulsed frequency,duty factor,peak current and base current were discussed,providing a convenient and intuitionistic means for the selection of optimum parameters in practical experiments and foundation for the application of the pulsed submerged-arc welding method.
