In this paper,the problems of arc wandering and instability have beenstudied with extra transversal magnetic field for low current TIG welding.Theinfluence of extra magnetic field frequency(0~10kHz)on the arc appeara-nce has been observed.The arc swing is in synchronism with magnetic fie-ld in low frequency,so the arc appearance is expanded.The arc is calmedin medium frequency,and is compressed in high frequency,thus increasingthe arc energy density,the arc stiffness and the arc voltage.When otherconditions remain unchanged,with increased intensity of magnetic field thesaid phenomena are intensified accordingly.Experiment results of weldingthin sheet indicate that by using magnetic field to control the arc,thewandering of arc can be restrained and the arc stability and shape improvedmarkedly.

本文针对小电流TIG 焊时,电弧漂移稳定性差问题,用外加横向磁场控制电弧进行了研究,观察外加磁场频率(0~10kH_2)对电弧形态的影响。外加低频磁场时,电弧与外加磁场同步摆动.电弧形态扩展;外加中频磁场对电弧有较强的镇定作用;外加高频磁场对电弧有明显的压缩作用,使电弧挺度增大,电弧能量密度及电弧电压数值增加。提高控制磁场强度.会加剧上述现象。焊接工艺实验结果表明,利用合理的交变磁场,能抑制电弧的漂移现象提高电弧的稳定性,明显地改善了薄板焊接工艺性能及焊缝成形。

In this paper, the self-maintaining arc in vacuum with hollow cathod and its application for welding and brazing were studied. The experimental results showed that for fusion welding, the vacuum arc is possessed of good stiffness, strong penetration and a good appearance of weld on both sides. The strength and plasticity of the joints welded by vacuum arc are much better than those of the joints welded by the traditional arc. And for brazing, the vacuum arc provides excellent flexibility, fast heating, easy controlling of parameters and high quality of brazed joints etc. As the duration at high temperature is very short, the harmful intermetallic compounds inside the joint could be avoided. Hollow cathod vacuum arc is a new kind of welding heat source which promises good prospect.

主要研究真空条件下的自持放电电弧(空心阴极真空电弧)作为新型热源用于熔化焊及钎焊的工艺适应性。研究结果表明,该热源用于熔焊时,电弧挺度大,穿透能力强,焊缝正反面成形好,接头强度及塑性指标均优于常规焊接方法。而将其作为局部加热热源用于真空钎焊时,又具有电弧柔性大、升温速度快、参数可控性好、焊缝成形好等优点。同时由于接头在高温停留时间短,焊缝组织中不易产生有害的金属间化合物及晶粒长大现象。空心阴极真空电弧是一种很有发展前途的新型焊接热源。
