| 摘 要： | 设计了一套水冷铜阳极装置,用压力传感器测量等离子弧焊阳极电弧力的径向分布情况,研究了焊接电流、离子气流量和弧长对阳极电弧力的影响规律.结果表明,阳极电弧力在电弧中心最大,随径向距离的增大而迅速减小,电弧力作用半径可以认为等于约束喷嘴出口半径;随焊接电流和离子气流量的增大阳极电弧力显著增大,电弧力作用半径变化不大;而弧长对阳极电弧力的影响不大;测量结果表明,等离子弧焊电弧力传统经验公式忽略电流对电弧力的影响是有一定缺陷的.

| Abstract: | In the present paper,a water-cooled copper anode was designed.The radial distribution of plasma arc anode pressure was measured by using pressure transducer.The infulence of welding current,ionized gas feed rate and arc length on anode arc pressure was studied.Results show that the maximum of anode arc pressure appears in the center of electric arc,which decreases rapidly with the increase of radial distance.It is considered that the arc pressure radius approximates the radius of restraint muzzle.The arc pr... |
