该方案不仅克服了传统方案存在的主维弧干涉现象，而且可大大降低钨电极的烧损，提高焊接过程的稳定性。
This scheme not only eliminates the interference between main arc and pilot arc, but also reduces the deterioration of the tungsten electrode and improves the stability of welding process.
钇钨电极在焊接时，弧束细长，压缩程度大，尤其在中、大电流条件下溶深最大，目前主要用于军工和航空航天工业。
Yttriated Tungsten is primarily used in military and aviation industry with narrow arc beam, high compressing strength, highest welding penetration at medium and high current.
我国是钨资源大国，钨电极在亚弧焊接中已得到广泛应用。
China is a country with rich tungsten resource, tungsten electrodes have been widely applied in the TIG welding.
