Product Selection Differences for Preground Tungsten

When selecting preground tungsten, there are several key differences to consider:

1. Tungsten Type: The most common types of tungsten electrodes are pure tungsten and various tungsten alloys like thoriated, ceriated, lanthanated, and zirconiated tungsten. Each type has different properties that make them suitable for specific applications.

2. Tip Geometry: The shape of the tungsten electrode tip can affect welding performance. Common tip geometries include pointed, balled, and truncated tips, each with their own advantages for different welding applications.

3. Grind Angle: The angle at which the tungsten electrode is ground affects arc stability and penetration. Common grind angles include 15, 20, and 30 degrees. The grind angle should be chosen based on the welding process and material being welded.

4. Size: Tungsten electrodes come in various diameters ranging from 0.040 inches to 1/8 inches. The size of the electrode will depend on the welding current and application requirements.

5. Coating: Some preground tungsten electrodes come with specialized coatings to improve performance and longevity. These coatings can help with arc starting, stability, and contamination resistance.

6. Brand and Quality: Consider reputable brands known for quality tungsten electrodes to ensure consistent performance and reliability.

7. Price: While price shouldn't be the only factor to consider, it's worth comparing prices from different suppliers to ensure you are getting a good balance of quality and cost.

When selecting preground tungsten electrodes, it's essential to consider the specific requirements of your welding application and choose the option that best meets those needs.
