摘要: 钨极惰性气体保护焊(TIG)技术是近年来广泛应用的焊接方法,其电弧稳定、焊接质量好、飞溅小,应用领域广泛。通过改变磁场频率、磁感应强度和焊接电流,研究TIG电弧行为。结果表明,无外加磁场的TIG电弧呈圆锥形,施加纵向磁场时,TIG电弧的上部收缩、底部轴向膨胀,呈钟罩形;施加交流纵向磁场时,TIG电弧轮廓明显变小,电弧尾端有明显的汇聚。

关键词: TIG, 纵向磁场, 磁场频率, 磁场强度, 焊接电流, 电弧形态

Abstract: Tungsten inert gas arc welding(TIG)technology is widely used in recent years,due to its arc stability, good welding quality, small spatter, widely used fields. TIG welding arc behavior is studied by varying magnetic field frequency, magnetic induction and welding current in the paper. The results show that the TIG arc without external magnetic field is conical, the upper part of TIG arc shrinks and the bottom part of TIG arc expands axially when applied longitudinal magnetic field. The arc profile becomes smaller obviously when applied AC longitudinal magnetic field, and there is obvious convergence at the end of arc.

Key words: TIG, longitudinal magnetic, magnetic field frequency, magnetic field strength, welding current, arc shape and trajectory
