| 摘 要： | 通过对熔滴过渡工过程的能量和动量分析，建立了熔滴热焓量在表面变形熔池内部的分布模式，以此为基础采用数值模拟技术研究了熔通过渡类型和表面活性元素对ＭＩＧ焊接熔池流场的影响，揭示了溶滴过渡类型和表面活性元素与ＨＩＧ焊接熔池流场的相互影响规律，并对计算模型的可靠性进行了实验验证。

| Abstract: | The distribution model of droplet heat content inside the surface deformed weldpools wasestablished through analyzing energy and momentum in metal transfer processes. Numerical simulationtechnique was employed to study on the effects of metal transfer model and surface active elements on fluidflow in MIG weldpools. The calculated results reveal the correlation among metal transfer model, surfaceactive element, fiuid flow in MIG weldpool. Experiments were conducted to verify the model. |
