with measuring dynamic temperature change of twin electrode, the heating and melting of twin electrode single arc welding was investigated.
通过测量双电极焊条的动态温升等试验方法研究了双电极焊条单弧焊中双电极焊条的加热和熔化。
rusults show that the arc static characteristic of twin electrode single arc welding is rising, the static characteristic curve goes up with the increase of the space between two cores.
结果表明,双电极焊条单弧焊具有上升的电弧静特性,静特性曲线随两焊芯间距的增大而上移;
two cores melting speed can keep consistence is very important for twin electrode single arc welding to be stabilized.
两焊芯熔化速度能否保持一致是双电极焊条单弧焊过程能否稳定进行的关键。
