What is 2 Thoriated Tungsten 3 32?

2% thoriated tungsten, often denoted as WT20, is a tungsten electrode alloyed with approximately 2% thorium oxide (ThO2). Tungsten itself is chosen for welding electrodes due to its exceptionally high melting point and durability. The addition of thorium oxide significantly enhances its electrical properties, making it a preferred choice for Direct Current (DC) welding applications, particularly on steel, nickel alloys, and titanium. The 3/32-inch diameter refers to the electrode’s thickness, a common size that balances fine detail control with sufficient current-carrying capacity for many welding tasks. These electrodes are known for their excellent arc starting, stability, and resistance to spitting, contributing to cleaner, more consistent welds. For welders in Winston-Salem and across the United States, sourcing reliable 2% thoriated tungsten electrodes is key to maintaining high standards in fabrication and repair work.

The Role of Thorium Oxide

Thorium oxide is added to tungsten to improve its electron emission properties. This means that at a given temperature, thoriated tungsten emits more electrons than pure tungsten. This characteristic leads to several key benefits for welding: easier arc starting at lower amperages, a more stable and concentrated arc, and reduced arc wander. The thorium oxide particles are dispersed evenly throughout the tungsten matrix, helping to maintain the electrode’s integrity even when subjected to high heat and current. While the benefits are substantial, it’s important to note that thorium is a radioactive element, requiring proper handling procedures and safety precautions, especially during grinding or when fine dust is generated. However, when used correctly in TIG welding, the risks are minimal, and the performance gains are significant.

Understanding the 3/32-Inch Diameter

The 3/32-inch (approximately 2.4 mm) diameter for a tungsten electrode strikes an excellent balance for many TIG welding applications. This size is versatile enough to handle a range of amperages, typically from around 75 to 150 amps, making it suitable for welding thin to medium-thickness materials like sheet metal, pipes, and various structural components. Its relatively fine diameter allows for precise control over the weld puddle, which is especially important for intricate work or when welding in tight spaces. Compared to smaller diameters (e.g., 1/16 inch), it can sustain higher currents without overheating as quickly, and compared to larger diameters (e.g., 1/8 inch), it offers better maneuverability and heat management for delicate tasks. This makes the 3/32-inch 2% thoriated tungsten a go-to choice for many professional welders in Winston-Salem and beyond.
