What Do You Know About TIG Tungsten Electrodes Used For Welding?

TIG refers to the tungsten Inert Gas, it is a process of arc welding. This type of welding process produces welds with non-consumable tungsten electrodes. The process of fabrication that is used for joining metallic items is welding.it is an effective, dependable, and economical method for joining similar materials permanently. There are different types of tungsten electrodes like ceriated tungsten, pure tungsten, lanthanated tungsten, and thoriated tungsten, these are commonly used to weld invertors. Tungsten inert gas welding is also known as gas tungsten arc welding. This is a non-consumable tungsten shielding process that is commonly used to join thin stainless steel. This is also used to weld non-ferrous metals such as aluminum, copper, and magnesium alloy. The TIG welding process includes tungsten electrodes with a filler rod. This welding process is comparatively slower than other types of welding processes. It can produce a very high-quality weld.

Key features:

  • A non-consumable tungsten electrode is used in the welding process.
  • Ideal for thin stainless steel materials.
  • It uses different shielding gases including helium (He) and argon (Ar).
  • The low distortion welding process
  • The operators have complete control of welding variables like heat
  • It does not leave slag and splatter signs.

Advantages:

  • Provide outstanding looking weld beads
  • The process is perfect for joining thin base metal because it has good heat control input.
  • Strong and powerful joints.

Disadvantages:

  • Practice is required
  • Expensive process
  • Slower than processes of other consumable electrode arc welding

Different types of TIG tungsten electrodes:

Thoriated Tungsten:

One of the most common tungsten electrodes is thoriated tungsten which is used for DC TID. The thoriated tungsten is used for DC mild steel welding, bronze, and other metals. It provides excellent performance as it is low-level hazard radiation. This works perfectly with inverter welders.

Ceriated Tungsten:

This type of tungsten electrode is one of the best substitutes for thoriated tungsten. It is designed for inverters and transformers. This needs less amperage to begin when transforming welding. This is applied to thinner metals. Ceriated tungsten is popular and uses to weld different metals in AC and DC modes both.

Lanthanated Tungsten

Another popular substitute for thoriated tungsten is lanthanated tungsten. The lifespan of this tungsten electrode is longer than other tungsten alternatives. It is used for both inverter and transformer technology on AC and DC modes both.
