The Pure Tungsten Electrode

Pure tungsten electrode is the earliest electrode used in argon arc welding, but under DC welding conditions, this type of electrode is prone to non arcing or unstable maintenance. This scenario can be significantly improved by adding rare earth oxides.Therefore, pure tungsten electrode is only used as a welding electrode under AC conditions or as a resistance welding electrode.

Pure tungsten electrodes have a minimum tungsten content of 99.5% and no alloying elements. Pure tungsten has a very high electron escape work, so compared to other alloy tungsten electrodes, pure tungsten electrodes are more difficult to arc and maintain the stability of the arc beam. In addition, due to its high electron escape work, the electrode tip temperature is high and grain growth is prone to occur, which will lead to unstable arc beams, more difficult arc initiation, and shorter service life. Pure tungsten is only used for AC welding, however, good DC options are also available.

Essential details:

Main Parameter:

The green undoped tungsten electrode was created specifically for light metal welding with sinusoidal alternating current. For welding with direct current, it is not appropriate. It is not advised to use the green pure tungsten electrode with inverter power sources because of its inertia and high work function, which impede the generation of a pure square wave. The E3® is the best alternative to the green tungsten electrode.

The Green color means:W – made of pure tungsten without any oxide component

Specifications:

1. Low steam pressure

2. low electrode resistance 

 

3. High elastic modulus

4. Good conductivity

5. Low thermal expansion

Main applications :

 

1. Gas tungsten arc welding

 

2.Lon arc welding

 

3.Cutting

 

4. In non consumable argon arc welding

 

 

The most widely used pure tungsten electrode is under AC welding. It is generally used for welding aluminum, and magnesium alloys (AC) are generally used under alternating current.

Pure tungsten electrode can also provide cleaning, and the solder ball becomes sharp when heated. This shape provides a balanced waveform for AC welding arc stability, which is particularly good.

Pure tungsten electrodes also provide good arc stability for sine wave AC welding of aluminum and magnesium. However, they are not used for DC welding. Pure tungsten electrodes are widely used in various industries for specific welding applications.

Packaging:

 

1.The conventional packaging for pure tungsten electrodes is ten pieces per box.

 

 

2.Backed by water-resistant paper

 

 

3.They were foam-covered and placed inside a plywood box.

 

 

4.Perfectly Sealed and fixed

Shipping:

• 1.In international trade, sea freight is the most often used means of transportation. Sea freight has the advantages of a vast transportation volume and low cost, particularly for huge quantities and large volumes of commodities.

  2. Air freight is more efficient and faster than sea freight, making it ideal for shipments with modest cargo volumes and high value.

  3.Railway travel is particularly appropriate for crossing continents and connecting many nations and regions due to its high safety standards and quick travel speeds.

  4. Reaching remote places or congested urban areas is easier and faster with highway transportation than with other modes of transportation.

  5. While limiting disadvantages, multimodal transportation can maximize the benefits of many forms of transportation.
