Tungsten Electrodes for TIG Welding

Benchmark Abrasives carries a full line of tungsten electrodes for TIG welding from 1/16 to 1/8” in a variety of different alloy options.   Tungsten electrodes are a crucial component in Tungsten Inert Gas (TIG) welding, known for their durability, high melting point, and superior performance in creating strong, clean welds. Here's our short guide on tungsten electrodes and their role in TIG welding:

Why Should You Choose Tungsten Electrodes?

Tungsten electrodes are favored in TIG welding due to their ability to withstand high temperatures without deteriorating. This makes them ideal for welding applications where precision and quality are paramount. The high melting point of tungsten ensures minimal contamination of the weld pool, resulting in clean, strong welds.

Types of Tungsten Electrodes

There are different types of tungsten electrodes available for TIG welding, each with unique properties suited for specific welding applications. Common types include pure tungsten, thoriated tungsten, ceriated tungsten, lanthanated tungsten, and zirconiated tungsten. Choosing the right type of electrode is essential for achieving your desired weld quality.

Tips for Selecting Tungsten Electrodes

When selecting tungsten electrodes you should consider factors such as the type of material being welded, welding amperage, and desired weld characteristics. Different electrodes offer varying levels of stability, arc starting properties, and performance in both AC and DC welding applications. Consult Benchmark’s Tungsten Electrode guidelines for the best electrode choice.

Maintenance and Care tips

Proper maintenance and care of tungsten electrodes are essential for optimal welding performance.

1. Ensure electrodes are clean and free of contaminants before each use.
2. Sharpen electrodes to a fine point to improve arc stability and weld quality.
3. Proper storage in designated containers can prevent damage and prolong electrode lifespan.
