What is Thoriated Tungsten in Welding?
Thoriated tungsten is a metal used as the plasma cutting electrode emitter for non-oxidizing plasma gas. The tungsten helps create an arc that is less likely to wander and provides a more stable current. The thorium adds mass to the tungsten, which makes it more durable and less likely to break. The thoriated tungsten is also less likely to oxidize, which makes it ideal for use in welding applications.
What is thoriated tungsten electrode?
A thoriated tungsten electrode is a TIG welding electrode with a small amount of thorium added to the tungsten. The thorium increases the electron emission of the tungsten, which makes it an ideal choice for use in DC welding applications. The thoriated tungsten electrode is less likely to oxidize and has a higher melting point than other tungsten electrodes, making it ideal for use in welding applications.
Why is thoriated tungsten used in welding?
Thoriated tungsten is used in welding because it is less likely to oxidize and has a higher melting point than other tungsten electrodes.
How does thoriated tungsten work?
Thoriated tungsten works by adding thorium to the tungsten. The thorium makes the tungsten more electron-emissive, which makes it an ideal choice for use in DC welding applications. The thoriated tungsten is less likely to oxidize and has a higher melting point than other tungsten electrodes, making it ideal for use in welding applications.
What are the benefits of thoriated tungsten?
The benefits of thoriated tungsten include its ability to resist oxidation and its high melting point.
What are the disadvantages of thoriated tungsten?
The disadvantages of thoriated tungsten include its potential to cause health problems if inhaled or ingested.
Why do we no longer use thoriated tungsten?
Thoriated tungsten is no longer used because of its potential to cause health problems if inhaled or ingested.
What are the alternatives to thoriated tungsten?
The alternatives to thoriated tungsten include yttrium-oxide, zirconium-oxide, and hafnium-oxide. These alternatives are less likely to cause health problems and are just as effective as thoriated tungsten.
What is a Thoriated welding rod?
A thoriated welding rod is a welding electrode that contains thorium. The thorium increases the electron emission of the electrode, making it an ideal choice for use in DC welding applications.
2% thoriated tungsten
2% thoriated tungsten is also known as EWTh-2 or WT20. It is a tungsten electrode that contains 2% thorium.
