What is pure tungsten electrode?

Pure tungsten electrode is an electrode used in tungsten inert gas welding (TIG), also known as gas tungsten arc welding (GTAW). Pure tungsten electrodes are made from 99.5% pure tungsten and are usually color coded green. They are known for their ability to withstand high temperatures and provide stable arc performance.

Pure tungsten electrodes are commonly used for welding materials that require a non-oxidizing environment, such as aluminum and magnesium alloys. Since they produce a focused and precise arc, they are also suitable for welding thinner materials.

Pure tungsten electrodes are not recommended for welding applications requiring higher current levels or for welding materials that form thick oxide layers, as they are more susceptible to contamination and may cause arc drift.

In summary, pure tungsten electrodes are designed specifically for TIG welding applications where a non-oxidizing environment and precise arc control are critical. They are ideal for welding aluminum, magnesium and other non-ferrous materials, making them a valuable tool in the welding industry.

What is the composition of tungsten electrode?

Tungsten electrodes used in TIG welding are typically made from a high proportion of tungsten, with small amounts of other elements added to enhance their performance. The most common components of tungsten electrodes include:

1. Pure Tungsten Electrodes: These electrodes are made of 99.5% pure tungsten and are usually color coded green. They are suitable for welding applications requiring a non-oxidizing environment, such as welding aluminum and magnesium alloys.

2. Thoriated Tungsten Electrodes: These electrodes contain a small amount of thorium oxide mixed with tungsten (usually 1-2%). They are usually color coded and have a red tip. Thorium electrodes are known for their excellent arc starting and stability, making them suitable for a wide range of welding applications.

3. Ceramic tungsten electrode: Ceramic electrode contains cerium oxide (usually 1-2%) and tungsten. Their color is usually orange. Ceramic electrodes have good arc stability and are suitable for both AC and DC welding, making them suitable for a variety of welding applications.

4. Rare earth tungsten electrode: Rare earth electrode contains a small amount of lanthanum oxide mixed with tungsten (usually 1-2%). Their color is usually blue. Lanthanum series welding rods have good arc starting properties and stability, and are suitable for AC and DC welding.

5. Zirconium tungsten electrode: Zirconium electrode contains a small amount of zirconium oxide mixed with tungsten (usually 0.8-1.2%). Their color is usually brown. Zirconium electrodes are known for their ability to resist contamination and are commonly used for AC welding of aluminum and magnesium alloys.

Each type of tungsten electrode has specific characteristics that make it suitable for different welding applications. The choice of electrode composition depends on factors such as the type of material to be welded, the welding current, and the specific requirements of the welding process.
