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。

Are given out, and then a survey and review of the literature up to 1980 is given of the linear theory of the ideal and resistive hydromagnetic instability of tokamak.
