WT20: 2% thoriated tungsten electrodes (AWS classification EWTh-2) contain a minimum of 97.30% tungsten and 1.70 to 2.20% thorium.
Tungsten electrode is a type of electrode that is widely used in welding, cutting, and other industrial applications. It is made from tungsten, a rare metal that is known for its high melting point and exceptional strength. Tungsten electrodes are commonly used in TIG (tungsten inert gas) welding, which is a type of welding that uses an inert gas to protect the weld area from atmospheric contamination. TIG welding is often used in the aerospace, automotive, and manufacturing industries, where precise and high-quality welds are required.
2% thoriated tungsten electrodes (AWS classification EWTh-2) contain a minimum of 97.30% tungsten and 1.70 to 2.20% thorium. They are the most commonly used electrodes today and are preferred for their longevity and ease of use. Thorium increases the electron emission qualities of the electrode, which improves arc starts and allows for a higher current carrying capacity. This electrode operates far below its melting temperature, which results in a considerably lower rate of consumption and eliminates arc wandering for greater stability. It also features a lower level of weld contamination than other electrodes. Unlike pure tungsten, these electrodes are only for specialty type AC welding (thin gauge aluminum or materials less than .060-in.), but they are exceptional for DC electrode negative or straight polarity on carbon and stainless steel, nickel and titanium applications. During manufacturing, thorium is evenly dispersed throughout the electrode. This evenness allows the electrode to maintain a sharpened edge-the ideal electrode shape for welding thin steel. Sharpening the electrode's point, however, should be done with great care.

Once a wire type is determined for your welding equipment, two additional pieces of information are needed in order to purchase this consumeable. The first is the wire diameter, which is usually given in thousands of an inch. The most common sizes for welding sheet metal are 0.35 and 0.45. The table below is commonly found in consumeable spec sheets and is worth copying for reference. It tells you how to set the controls on your equipment and which gas you need, depending on the welding process.
