Tungsten
Tungsten electrodes are used during arc welding with the Tungsten Inert gas (TIG) process or when plasma welding. In both processes, the electrode, arc, and weld pool are protected from atmospheric contamination by an inert gas.
A tungsten electrode is used because it can withstand very high temperatures with minimal melting or erosion. Electrodes are made by powder metallurgy and are formed to size after sintering.
TIG welding electrodes usually contain small quantities of other metallic oxides which can offer the following benefits :
- Facilitate arc starting
- Increase arc stability
- Improve current-carrying capacity of the rod.
- Reduce the risk of weld contamination
- Increase electrode life
Below is a table describing the differences in TIG electrode types, and you can find the full product line with us:-
| Thoriated | Red | The red Thoriated type is the most used electrode for a reason. Extremely long-lasting and highly durable, these electrodes are a staple in DC welding applications. These red electrodes are best for copper alloys, nickel alloys, titanium alloys, and non-corroding steels. |
| Zirconated | White | White Zirconiated tungsten electrodes handle higher amperage levels and work well with both transformer and inverter power sources, making them an excellent alternative to the green pure tungsten electrodes for magnesium and Aluminium alloys. |
| Ceriated | Grey | Grey Ceriated electrodes are popular due to their extreme ease of striking an arc with lower amperages, and their extraordinary performance with regard to DC welding applications. They perform best with titanium alloys, copper alloys, magnesium alloys, Aluminium alloys, nickel alloys and low-alloyed steels. |
| 1.5% Lanthinated | Gold | The gold Lanthinated tungsten electrodes contain less lanthanum than their blue counterparts and are best used in DC applications. They are best for welds with titanium alloys, copper and nickel alloys. |
| 2% Lanthinated | Blue | The blue lanthanated electrodes are popular due to the relative ease of striking an arc and lower amperage required. They perform exceptionally well in both AC & DC applications and are a popular general use electrode. Blue electrodes are effective for welding Aluminium alloys, magnesium alloys, nickel and copper alloys. |
| Pure Tungsten | Green | The original green pure tungsten electrode contains at least 99.5% tungsten and delivers all of the properties classically associated with tungsten – superior conductivity, durability, and performance. Green electrodes are perfect for weld projects containing magnesium or Aluminium alloys. |
Oxides used are primarily those of zirconium, thorium, lanthanum, yttrium or cerium. Additions are usually of order 1%-4%. All these oxides greatly improve arc initiation, especially when direct current (DC) welding is employed.
