纯钨极
钇钨极
复合极
PURE TUNGSTEN/YTTRIATED TUNGSTEN/COMPOSITE ELECTRODES
特色：1、纯钨电极在所有的钨电极中价格***便宜，适合在交流条件下镁、铝及其合金的焊接。
2、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***大，目前主要用于***和航空航天工业。
3、复合电极是在钨中添加了两种或更多种的稀土氧化物，各添加物互为补充，相得益彰，使其焊接性能更出众。
Characteristics:1.pure tungsten,the least expensive of all tungsten,is generally used in the AC welding of aluminum and magnesium alloys.
2.Yttriated Tungsten is primarily used in military and ***iation industry with narrow arc beam,high compressing strength,highest welding penetration at medium and high current.
3.The performances of Composite Electrodes in welding can be much improved by adding two or more rare earth oxides which are mutually completementary.
