1、Characteristics
1)Pura Tungsteno , 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 aviation 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.
