Double Wires Submerged Arc Welding Temperature Field Simulation

摘要：

　　Double wires submerged arc welding is more and more widely applied.However,due to the immaturity of the welding process,the quality of double wires submerged arc welding is still not so good,and its application in the offshore platform engineering is limited.The paper adopt the simple flat plate welding,uses the finite element software ANSYS to simulates the temperature field of double wire submerged arc welding process.During the temperature field simulation process,double ellipsoid heat source model is used as a load heat source,composite convection coefficient is adopted to simulate heat loss,the elements birth and death is considered to simulate welding material injection,welding speed is assigned as a constant.At last,a good result of temperature field is obtained.
