What is Purple Tungsten Used for?
Tungsten is an extremely hard and fragile material. The main properties incorporate an exceptionally high softening point, a low fume pressure, and the most elevated hardness and strength, everything being equal. Notwithstanding the exceptionally high thickness and warmth obstruction, tungsten has awesome electrical and warm conductivities. Tungsten has great erosion obstruction against most acids and soluble bases.
Tungsten electrodes are utilized for welding measures, for example, in opposition welding, particularly when materials like copper, bronze, or metal are welded. The new tungsten terminal will ultimately turn into the main tungsten as Thoriated electrodes become more diligently imported because of the radioactive substance.
What is Purple Tungsten Used For?
The purple tungsten electrode is a genuine non-radioactive option in contrast to the thoriated tungsten electrode.
- The E3 electrode, as it is known, has many advantages
- The electrode tip stays cooler than its thoriated cousin
- It has prevalent repeatable start attributes
- Has expanded circular segment dependability
Advantages of decreased consumption off
- Can convey a higher current than the other options
- Further developed tip degradation of the electrode tip
For instance - when utilizing a similar current thickness, the E3 electrodes are around 900 degrees C, not exactly a 2% Th (Red Tip) tungsten. Not something to be sniffed at.
The imaginative Rare Earth Blend tungsten electrode contains 98.34% tungsten, 1.5% lanthanum, 0.08% Zirconium, and 0.08% Yttrium. It is the ideal substitute for red thoriated electrodes. They perform well in DC applications and are extraordinary for welding copper combinations, nickel compounds, titanium amalgams, and tempered steel.
Other Applications of Purple Tungsten
Some of the key applications of purple tungsten are as follows:
- TIG Welding: due to its flexibility, outstanding ignition, and welding properties, purple tungsten is preferred for TIG welding. It can be used for welding various metals like aluminum, nickel, titanium, copper, non-alloyed and high-alloyed steel.
- AC & DC Welding: Purple tungsten is also a popular choice for AC & DC welding.
- Automated welding: It is also widely used for welding processes because of its reliable ignition properties.
Why Is It Called Purple Tungsten?
The various types of tungsten electrodes are usually recognized by their color code. This is why it's called purple tungsten. it does not define any properties.
Benefits Of Purple Tungsten
The following are the benefits of using purple tungsten:
- Outstanding Ignition: it quickly creates an arc even at lesser currents.
- Versatility: Can be applied to a wide range of applications and metals.
- Long shelf life: if compared to other tungsten types, these provide excellent electrode life.
Effects of Different Tungsten Components
- Zirconium oxide keeps the vanishing lower and empowers a more steady bend contrasted with unadulterated tungsten electrodes.
- Cerium oxide gives a tungsten terminal excellent start and reignition properties.
- Lanthanum oxide has great start properties and gives the electrodes a more drawn-out help life.
- Thorium oxide makes a truly steady bend; anyway, it is radioactive, which implies it is extremely hurtful to wellbeing. When thorium smoke or residue is breathed in, it very well may be stored in the lungs and lead to inward radiation exposure. As an outcome, it has been restricted as an added substance to tungsten electrodes in numerous nations.
Rare Earth Mix Tungsten Electrode (WP green) empowers an exceptionally consistent circular segment. At the same time, oxide-containing electrodes are simpler to touch off, have a high current conveying limit, and have a more extended assistance life.
