在焊接過程中，等離子氣流對熔池的沖擊力直接影響到液態金屬的流動以及焊縫的后質量，對等離子流力的測量和分析也多見于文。在單面焊雙面成型過程中，在沒有小孔存在的情況下，電弧吹力在熔池表面產生氣體剪切力 ,當出現小孔后，電弧吹力除了在熔池表面產生氣體剪切力以外，還會在小孔內部的液態金屬自由表面產生另外一個剪切力 ,對熔池流體的流動產生影響，促使工件表面的液態金屬向小孔中流動，電弧吹力的作用也會增加焊縫中間部位的寬度，有利于形成良好的焊縫質量。
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.
