| 摘 要： | 开发了一种耦合电弧钨极,可显著降低电弧压力,消除咬边和驼峰焊道等缺陷,实现较高速度的TIG焊接.针对这种钨极进行了TIG电弧压力测量,研究了主要工艺参数对电弧压力分布的影响规律.结果表明,与传统TIG电弧相比,在相同参数下耦合电弧钨极TIG电弧压力峰值明显降低,并且随着弧长的增加、钨极伸出长度的增加、焊接电流的减小、电极槽宽的增大以及钨极直径的增大,耦合电弧钨极TIG焊的电弧压力峰值减小.对电弧压力的影响由大到小依次为焊接电流、钨极伸出长度、弧长和钨极直径、电极槽宽.

| Abstract: | A kind of coupling arc tungsten electrode was developed to decrease arc pressure remarkably,avoid undercut and humping weld.Adopting this method, high-quality TIG welding with relative higher speed can be achieved.The TIG arc pressure of this kind of welding process was tested to investigate the influence of the parameters on distribution of arc pressure.Compared with the traditional TIG arc,the TIG arc pressure with coupling arc electrode is much lower with the same parameters, and decreases with the increase of arc length,the increase of electrode extended length,the decrease of current,the increase of the electrode gap width and the increase of the electrode diameters.The arrangement of the influence in decreasing order is current, electrode extended length,arc length and electrode diameter, electrode gap width. |
