Classification of Tungsten Electrodes
Tungsten lanthanum electrode: lanthanum oxide is added to tungsten to produce tungsten lanthanum electrode.
Tungsten lanthanum has the following advantages:
Better mechanical cutting performance, better creep resistance, high recrystallization temperature and good ductility.
Tungsten lanthanum electrode is now the most popular electrode material in the world, especially for lanthanum electrode with a content of 1.5% (which is different from the content of 2%).
Scientific studies have shown that the conductivity of 1.5% tungsten lanthanum is close to that of 2% tungsten thorium, therefore, welding personnel can easily replace electrodes without changing the parameters of the equipment. Tungsten lanthanum electrode is also suitable for AC welding, and the performance is excellent.
Tungsten thorium electrode: Tungsten thorium is produced by doping thorium oxide in tungsten. Compared with pure tungsten materials, tungsten thorium has the following characteristics:
1. Electronic function is lower
2. The crystallization temperature is higher
3. Better conductivity
4. Good mechanical cutting performance
Tungsten thorium electrode is a widely used tungsten electrode material, it has better weldability than pure tungsten and is widely used in the field of direct current welding. Tungsten thorium electrode is easy to operate and can operate well even under overload current. Many companies still use this material. It is considered as a part of high quality welding.
Tungsten yttrium electrode: When welding of tungsten and yttrium electrode, the arc beam is elongated and compressed, and it has a great penetration in the medium and high current. It is mainly used in military industry and aerospace industry at present. Zirconium oxide is doped with zirconium oxide in tungsten to produce tungsten zirconium electrode.
Zhengzhou Sanhui has been specializing in the producing of tungsten, molybdenum, tantalum, niobium, titanium and other products. Our products include tungsten alloy series, tungsten product series, molybdenum product series, tantalum product series, niobium product series, rare metal series, hard alloy series and other products.
