- Abstract:
- Based on the APDL( ANSYS Parametric Design Language ) of commercial finite element softwareANSYs and selecting the double-ellipsoid heat source model,the finite element model of (345B plate T-jointmulti-layer and multi-pass welding is created. With the element birth and death technology and simulating thefilling process of weld material by programming subroutine which activates the welding element step by step.The temperature field distribution regularities of the model under different welding speeds are analylized andworked out the thermal cycling curves of typical positions.The simulation results are verified through experi-ment which prove the reliability of the welding simulation and provide some theoretical help to analysis the ac-tual welding process.
