The experimental results indicated that the longer the po uring intervallic time of the two kinds of molten metal and the higher the heigh t of the molten iron to pour into the tip of dipper teeth , the narrower its tran sitional zone will be, on the contrary, the wider its transitional zone will be.

用不同粘度的流体通过水力模拟的方法近似地描述了双金属斗齿过渡区的混合状态。试验结果表明：两种液体浇注的间隔时间越长，先浇入的铁液液面越高，过渡区越窄；反之，过渡区越宽。生产中为了保证过渡区双金属的结合质量，应控制较高的铁液液面高度及一定的双液间隔时间

The droplet transfer of twin-wire co-pool gas shielded metal arc welding process takes great effects on the behavior of the molten pool by transferring energy, momentum and fluid flow to the molten pool which will affect the weld appearance.

双丝共熔池GMAW(twin-wire co-pool gas shielded metal arc welding， TCGMAW)熔滴过渡对焊缝成形的影响体现在对熔池的作用上，熔滴对熔池的作用在于向熔池传输能量、动量和质量，最终会影响到焊缝的成形和质量。

The result shows that, when a free droplet transfer mode is applied in high-speed welding , the workpiece is heated by the arc throughout the process and thus the molten pool can not solidify in time.As a result, the molten pool is very long, which gives way to the instability of bead formareron and pinch effect of the liquid metal,so that it finally leads to the humping phenomenon. Based on the analysis and experimental result, the short-circuiting transfer mode is suggested to improve the bead formation in high-speed welding .

理论分析和试验结果均表明，采用自由过渡的熔滴过渡形式进行焊接，工件始终处于焊接电弧的加热下，在高速焊接时，熔池不能及时冷却，熔池明显拉长，由扰动引起的振动波长大，当熔池的拉长达到一定程度时，会发生液体金属的失稳和颈缩的现象，造成驼峰焊道。

There is no essential difference between the two, as the pool of metal around the hole surrounded by molten metal gravity and surface tension have to make holes to bridge the trend, while the metal vapor is generated by a continuous attempt to maintain the existence of holes.

从机理上看，这两种焊接方法的前提都是焊接时存在小孔，两者没有本质的区别，小孔周围为熔池金属所包围，熔化金属的重力及表面张力有使小孔弥合的趋势，而连续产生的金属蒸气则力图维持小孔的存在。
