通过对熔滴过渡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滴过渡类型和表面活性元素对MIG焊接熔池流场的影响，揭示了溶液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
Based on the energy and momentum analysis of the droplet transfer process, the distribution pattern of the droplet enthalpy in the surface of the weld pool was established. Based on this, numerical simulation was used to study the effect of the type of droplet transfer and surface active elements on MIG welding The influence of the flow field of molten pool, the interaction between solution transition type and surface active elements and HIG welding pool flow field are revealed, and the reliability of the calculation model is verified by experiments
