在焊接过程中，等离子气流对熔池的冲击力直接影响到液态金属的流动以及焊缝的后质量，对等离子流力的测量和分析也多见于文。在单面焊双面成型过程中，在没有小孔存在的情况下，电弧吹力在熔池表面产生气体剪切力 ,当出现小孔后，电弧吹力除了在熔池表面产生气体剪切力以外，还会在小孔内部的液态金属自由表面产生另外一个剪切力 ,对熔池流体的流动产生影响，促使工件表面的液态金属向小孔中流动，电弧吹力的作用也会增加焊缝中间部位的宽度，有利于形成良好的焊缝质量。
In the welding process, the impact force of plasma flow on the molten pool directly affects the flow of liquid metal and the post weld quality. The measurement and analysis of plasma flow force are also seen in this paper. In the process of single-sided welding and double-sided forming, when there is no small hole, the arc blowing force generates gas shear force on the surface of the molten pool. When there is a small hole, the arc blowing force not only generates gas shear force on the surface of the molten pool, but also generates another shear force on the free surface of liquid metal inside the small hole, which affects the flow of fluid in the molten pool, Promote the liquid metal on the workpiece surface to flow into the small hole, and the arc blowing force will also increase the width of the middle part of the weld, which is conducive to the formation of good weld quality.
How to improve the specific performance of plasma automatic welding
If the operation method is incorrect, it will naturally affect the use of plasma automatic welding. You can also understand how the performance of its parts works. Plasma automatic welding can also avoid damage to power cables, which may cause accidents and losses. In order to ensure the quality of plasma automatic welding, of course, you can also understand the later efficiency of plasma automatic welding, Because if we can ensure the better use of plasma automatic welding, it can take a relatively long time. In practical application, if the equipment has good after-sales service, the changes made by plasma welding are relatively large.
At present, in the field of electric welding machine, especially in the field of uniform welding plasma welding machine, the technical solution is that the plasma welding machine can weld the main body evenly, and when to place the device. When the welding wire is closed, the main body of the welding machine is also equipped with mechanical cables. In order to make the cables of the cable arrangement mechanism evenly arranged, the current plasma welding machine technology has been very mature, Many welding problems have been solved.
