用三维不可压缩光滑粒子流体力学方法模拟了气体保护焊熔池对流和焊缝成形过程。此外，还采用系综平均处理方法研究了熔池速度场的动态变化。结果表明，熔滴过渡对熔池速度场有影响，特别是垂直方向距熔池表面约3 mm，水平方向距热源中心约 ± 5 mm的区域。
The weld pool convection and the bead formation in a gas metal arc welding were simulated by a three-dimensional incompressible smoothed particle hydrodynamics method. Moreover, the ensemble average processing was carried out to investigate dynamic changes of the velocity field of a weld pool. From these results, it was formed that the droplet transfer affected the velocity field of the weld pool, especially the region which was about 3 mm from a weld pool surface in the vertical direction and about ± 5 mm from center of the heat source in the horizontal direction.
