What should the tungsten electrode look like after it has been cleaned and pointed?

After cleaning and pointing, the tungsten electrode should appear shiny and sharp. A shiny surface indicates that any oxides or contaminants have been effectively removed, allowing for optimal electrical conductivity. A sharp point enhances the precision of the arc during the welding process, which is crucial for maintaining control over the weld bead and achieving the desired penetration and bead shape.

The point of the tungsten electrode is designed to focus the arc, and a well-shaped, sharp tip allows for a more stable and concentrated arc, which is essential for high-quality welds. This characteristic is particularly important in Gas Tungsten Arc Welding (GTAW), where the quality of the weld depends significantly on the stability of the arc and the heat input to the workpiece. A dull or poorly shaped electrode could lead to erratic arc behavior and inconsistent welds, affecting the overall quality of the finished work.
