| Abstract: | The calculating formula of Gaussian model in double wire welding is derived according to the superimposition principle,and the proper finite element model is constructed,the transient change of temperature field is simulated in high speed welding processes.At the same time,the motions of welding heat resource are actualized by the means of programming in APDL of ANSYS and saving the heat flux matrix using table array,then forming uniform face load.Finally the simulated results of the fusion are shown. |
