摘　　要：为研究附加机械力的 ＭＡＧ焊射滴过渡机制，本文在建立了适合于“Ｓｕｒｆａｃｅ Ｅｖｏｌｖｅｒ”软件的 能量模型的基础上，实现了射液过渡行为的有限元分折．着重就熔液体积、焊丝直径、焊接电流及 表面张力作用等因素对射滴过渡行为的影响进行了分析与讨论，从理论上证明了施加附加机械力 是实现稳定射滴过渡的有效途径．An Energy model, suitable for the software of surface Evolver, was firstly established for studying the projected transfer mechanical force in MAG welding. The project transfer FEM was realized using the model. The effect of different welding factors in the process of realizing project transfer is discussed. Theoretic analysis shows it is an effective way to attain stable Projected transfer by utilising additional mechanical force.
