本文从交流电弧在“零休”时间能量平衡过程出发,分析了交流电弧燃烧的稳定性,并由此建立了一个评定交流电弧燃烧稳定性指标;为了扩大交流电弧应用范围,以适应碱性焊条手弧焊及熔化极交流气电焊工艺之需要,研制了一个双向电压脉冲稳弧装置;并用此装置与普通国产交流弧焊机相结合进行了上述两种工艺实验,对实验中有关交流电弧燃烧稳定性方面的问题做了初步探讨。
In this paper, starting from the energy balance of AC arc at “zero off” time, the stability of AC arc combustion was analyzed and an index to evaluate the stability of AC arc combustion was established. In order to expand the application range of AC arc, Hand arc welding and melting pole AC gas welding process needs, developed a bidirectional voltage pulse arc stabilizing device; and with this device and the common domestic AC arc welder combined the above two kinds of process experiments, the experiment on the AC arc combustion Stability of the issue made a preliminary discussion.
