Can't say I've even saw anything but thoriated and pure in the ones I've worked in. It has a low work function and provides a high load and amperage capability. The general consensus of users is that ceriated or lanthanated tungstens are acceptable alternatives to thoriated tungstens, particularly with a DC current, while zirconiated tungsten is preferred for AC current welding. It can even do AC welding. Lanthanated tungsten can be used for all of the DC welding applications with excellent arc stability at low amperages while maintaining its sharp point well and minimal burn rate in high amperage situations. WLa plasma spray electrodes exhibit excellent resistance to both arc erosion and high temperature and possess superior heat conductivity. The TIG electrode is consumed in the welding process but the material does not form part of the weld. After a few dips in the pool, it's off to the grinder (again). The thoriated electrode is sometimes called 2 percent because it contains thorium to that specific amount, while the lanthanated electrode is 1.5 percent because it contains lanthanum. The physical appearances of the two tungsten materials differ due to their color. The two tungsten materials have differences in physical appearance and other features and similarities that make them in the same category.

Both tungsten metals have an arc in them that helps them enhance the arc welding process for the metals. 2% Lanthanated tungsten is among the most commonly used non-radioactive tungsten. As the high temperature strength of the Lanthanated Tungsten Electrode is very good, it is necessary to use a higher process temperature in the process of pressure processing. A good tungsten for pulsing or welding that requires frequent re-ignitions with a short weld cycle. We tested lanthanated against thoriated and found that lanthanated was ALWAYS just as good as thoriated and sometimes actually even better. manufactured to exact specifications, this 10-pack of 2% lanthanated tungsten electrodes (blue, ewla-2) offers superior quality and low-cost value while adhering to ansi and aws standards. The number of electrons in each of tungsten's shells is [2, 8, 18, 32, 12, 2] and its electron configuration is [Xe] 4f 14 5d 4 6s 2. Unless i am wrong about something i see no question which tungsten is right for me. At elevated temperatures (i.e., when red-hot) it reacts with oxygen to form the trioxide compound tungsten (VI), WO 3. CHEMETAL USA has the capacity to manufacture W-La2O3, W-CeO2, W-Y2O3, and other oxidized rare earth tungsten rods. more thermal shock which provides the user with excellent ignition and a low burn off rate. Most existing human toxicology information comes from chronic occupational exposure. The tungsten electrodes doped with thorium oxide are an emitter of alpha particles. We recommend lanthanated tungsten as the best tungsten for welding aluminum and just about any other metal as well. This design gives the Lanthanated Tungsten optimal stability, life, arc, and versatility. The short answer is, In this guide, we will walk you through the. Is Ceriated tungsten radioactive? 2% Lanthanated (Blue) Blue electrodes are effective for welding aluminum alloys, magnesium alloys, nickel alloys, . Good for low-alloyed steels, non-corroding steels, aluminum alloys, magnesium alloys, titanium alloys, nickel alloys, copper alloys. Tungsten has been the subject of numerous in vivo experimental and in vitro studies in view of determining its metabolic and toxicity profile. If you were to purchase a variety of tungsten options, you would find that you need a variety of types and sizes. Thoriated tungsten is the most commonly used in the United States. . Before choosing the best electrode to use, consider checking on some things. Welding professionals choose to use lanthanated electrodes because they facilitate arc starting well, carry the current efficiently, and withstand quite a few arc cycles. Therefore, Lanthanated tungsten electrode exhibit excellent arc starting, stability, and re-ignition, electrode life, as well as a low risk of weld contamination, especially when direct current (DC) welding is applied. It has a good resistance to wear and erosion, and it also has a low coefficient of friction. This tungsten is used primarily in DC welding. Weld process is also very similar (I am told). It contains minute levels of radioactive material. The first one, introduced in the 1980's, is most commonly available as 2% ceriated tungsten. 2% Lanthanated (Blue) Blue electrodes are effective for welding aluminum alloys, magnesium alloys, nickel alloys, copper alloys, . Nonwelders typically are the ones telling us we have "viable alternatives." Granted, these days the lanthanated and ceriated tungsten electrodes are way more refined than they were even just 10 years ago. The zirconated tungsten has a stable and steady arc that has very little tungsten spitting to it. Argon welding is very popular among both industrial and, The materials you need for your TIG (or any, Choosing the right tungsten for the job is almost. "manufactured to exact specifications, this 10-pack of 2% lanthanated tungsten electrodes (blue, ewla-2) offers superior quality and low-cost value while adhering to ansi and aws standards. Add to cart. Now, we have got a complete detailed explanation and answer for everyone, who is interested! The tungsten and lanthanum powders must be at least 99.95% pure; they must be composited evenly and uniformly; pressing must occur at 160-200 MPa; hydrogen sintering is conducted for 6 hours at an operating temperature of 2300-2400. They are both great options but you should know and understand the limitations of 1.5%. Therefore, Lanthanated tungsten electrode exhibit excellent arc starting, stability, and re-ignition, electrode life, as well as a low risk of weld contamination, especially when direct current (DC) welding is applied. It has the ability to resist thermal shock which provides the user with excellent ignition with a lower burn off rate. This tungsten is primarily used for DC welding, but will also show good results for AC welding. as long as shovelon, but agree with him, thoriated is the king for DC TIG, even though it is technically slightly radioactive and you want to avoid breathing in or eating the grinding . The valuable properties of oxide lanthanum allow Lanthanated tungsten electrode has well-balanced oxide evaporation and migration rate at a low electron work function. The answer is everything! There are many different factors to consider when choosing electrodes for use in the welding industry. I figure the risk/exposure must be very low, they still issue thoriated every day in the nuclear power industry. 1.5% Lanthanated TUNGSTEN ELECTRODE AWS A5.12 Class EWLa-1.5 Lanthanated tungsten is for TIG welding most metals. It just sucks that local shops dont stock it. I try to only use Lanthanated, but I have some Thoriated in the mix that I keep presharpened. The cerium electrodes function admirably with the Advanced Squarewave power sources and should be ground to an altered point. Suitable for both Alternating Current (A/C) or Direct Current (D/C) using inverter or transformer based constant current power sources. I don't take long welding with AC to tell a difference. This is a question our experts keep getting from time to time.
