Tungsten electrodes come in several types, each adapted to specific applications:
- Pure tungsten (WP) Used for general applications, offering good resistance to heat and wear.
- Thoriated tungsten (WT) : Containing 1 to 2% thorium, they deliver better ignition performance and greater arc stability.
- Tungsten ceria (WC) : These electrodes, containing 2% cerium, are ideal for applications requiring low heat emission and excellent arc control.
- Tungstène lanthané (WL) Offering longer service life and good resistance to erosion, they are particularly well suited to high-frequency welding applications.
TIG welding, or Tungsten Inert Gas, is an arc welding process that uses a tungsten refractory electrode. This type of welding is particularly popular for its ability to produce clean and precise welds, thanks to the use of an inert gas that protects the intense heat of the process.
This tool is often preferred for welding non-ferrous metals such as aluminum and certain stainless steel grades. Indeed, this technique is distinguished by its versatility and ability to work with different materials, making complex alloys more accessible.
In the context of TIG welding, the role of inert gas should not be underestimated. Argon is generally used to wrap the electric arc and prevent oxidation of the welded joint. Thus, it guarantees optimal strength and an unimpeachable aesthetic appearance.
By providing a protective atmosphere, the gas allows controlled fusion that limits defects materialized in the form of cracks or inclusions. This control of the process is essential when the current used tolerates little inaccuracies.
Tungsten electrodes are at the heart of the success of TIG welding. Their high heat resistance makes them the perfect tool to withstand extreme temperatures without deteriorating. This material ensures a long service life, thus avoiding frequent stops related to the replacement of electrodes.
Different tungsten grades can be selected according to the project specifications. For example, some alloys allow better arc stability or facilitate low current starting. This tactical choice has a direct influence on the accuracy of the final work.
The robustness of tungsten electrodes gives them an appreciable service life in various industrial applications. Careful maintenance and proper use further extend this longevity, thus optimizing operating costs and increasing the productivity of welding operations.
Demystifying the maintenance of the electrode is then to understand the thermal cycles it supports. Ensuring proper heating management makes possible a continuous evolution of its daily performance.
