一、高效“双弧等离子”焊接原理高效“双弧等离子”焊接原理,就是在已引燃的万度以上超高温等离子弧中,自动送进通电焊丝,由焊丝与工件再产生一个电弧,把这两个电弧合为一体进行焊接的方法,就称为高效“双弧等离子”焊接。等离子弧可采用脉冲引弧或高频振荡器引弧,而焊丝与工件之间的电弧,只要在焊丝与工件之间加上80～100伏的电压就可以顺利的引弧了。高效“双弧等离子”焊接原 First, the efficient “double arc plasma” welding principle Efficient “double arc plasma” welding principle is in the already ignited thousands of ultra high temperature plasma arc, automatically sent into the power wire, the wire and the workpiece to produce an arc, the The two arc together as a method of welding, called efficient “double arc plasma” welding. Plasma arc ignition can be used pulse or high-frequency oscillator arc, and the arc between the welding wire and the workpiece, as long as the welding wire and the workpiece plus 80 ~ 100 volts voltage can be a successful arc.
