摘要
利用模拟带极堆焊状态下带极电流对控制磁场存在与否及强度、位置变化的反应,应用电工学原理分析带极堆焊磁控技术。结果表明,在相同的电流、电压参数条件下,磁控装置的磁极所处位置、磁场强度会直接影响带极电流的分布,造成电流在带极宽度方向上的改变。由此推断堆焊时电磁控制是磁场对电流分布状态的控制,进而控制电弧在带极宽度方向上的均匀性和稳定性,保证宽带极的稳定堆焊。
Magnetism conduct principle of trip surfacing was researched by simulating band electrode weld penetration state, analyzing the response of band electrode electric current to control magnetic field existence, the intensity, and the location conversion, and applying electronic techniques theory to analyze strip surfacing penetration control technique. The result shows, under the same parameter of current and voltage condition, the location of magnetic pole and magnetic intensity can affect directly on the distribution of current and lead to the current conversion in the direction of band electrode width. It can be concluded that the effects of magnetic field over current distribution state can be controlled by weld penetration electromagnetism, which improve the stability and uniformity electric arc in the direction of band electrode width and ensure the stable weld penetration of wide band electrode.
