Diameter And Geometry Affect An Electrode’s Electron Flow Behavior

The Ag Agcl Reference Electrode made of tungsten plays a crucial role in the process of orbital TIG welding. By using it, you can obtain the much-needed electric arc that influences the quality of the weld directly. You’ll also have to keep several points in mind when selecting an electrode. Some of these include the material used in making it, diameter, length, geometry, size, and surface condition.

The purpose

You need to sharpen the electrode as it’s the most important parameter. It dictates the characteristics of the geometry and welding arc. If you sharpen it, the electrode will facilitate the arc initiation. However, it can also deteriorate quickly, which, in turn, will cause potential tungsten incisions in the weld.

The flat spot

The flat tip of this electrode can extend its life. However, you need to do it correctly to ensure it doesn’t become too large. Otherwise, it’ll make the arc unchanneled and unstable. Therefore, you need to resort to an adapted flat tip to achieve arc stability, better electron transfer, and extended electrode life. All this will be achievable without risking tungsten inclusions.

The electron flow behavior

The diameter of the electrode used in TIG welding is as mandatory as the diameter of the one installed in an Electrochemical Cell. This value will determine the flow of electrons in the electrode. If you can supply more amperes, you’ll receive a greater flow. Conversely, if the flow is larger than the flat tip, the electrons will disperse and diffuse perpendicularly. As a result, the width of the heating zone will increase and lose its efficiency.

Final words

The only way to make sure that you use the right electrode is to determine the diameter and geometry. These two values will affect the probe’s arc stability, electron transfer, and shelf life.
