Make sure you use a tungsten electrode large enough in diameter to carry the welding current you plan to use. Thoriated (Color Code: Red) - Thoriated tungsten electrodes (AWS classification EWTh-2) contain a minimum of 97.30 percent tungsten and 1.70 to 2.20 percent thorium and are called 2 percent thoriated. The electrodes offer . 10pcs/Set Tungsten Electrodes WT20 Welding TIG Red Tip Rod Thoriated Weld AU $16.47 AU $18.72 Free postage RED 2% Thoriated Tungsten for TIG Welding TIP Electrode 150mm WT20 AC/DC 10pcs AU $17.00 Free postage 10PCS WT20 TIG Welding Thoriated Tungsten Electrode Rods High Conductivity AU $16.86 AU $18.94 Free postage Subscribe to our newsletter to receive the latest news and events from TWI: Tungsten electrodes are used when arc welding with the Tungsten Inert gas (TIG) process or when plasma welding. As a replacement to tungsten thoriated electrodes, electrodes with larger concentrations of lanthanum oxide can be used. During the grinding process, particles of tungsten may be produced with thoria on the surface. Even so,People gradually turned to other types of tungsten electrode.For example, the cerium tungsten and tungsten lanthanum.This is not just because they are in most applications have demonstrated excellent performance, but more importantly they have no radiation damage.Because thorium oxide in thorium tungsten electrode will produce trace amounts of radiation,The welding personnel would not close to them. They are the most commonly used electrodes today and are preferred for their longevity and ease of use. 2% Thoriated Tungsten contains a nominal 2 wt-% or thorium oxide (ThO2) that is evenly dispersed throughout the entire length of the Tungsten. Assembling tungsten oxide hydrate nanocrystal colloids formed by laser ablation in liquid into fast-response electrochromic films. Thoriated tungsten electrodes remain the only qualified electrodes for certain high-specification welding. When I first tried those other alloyed electrodes, it was near the beginning of the industry's search for alternatives.

There are very minor differences in the arc voltages required for equal currents between the various alternatives.

Thoriated Tungsten is the most commonly used tungsten electrode worldwide and are used mainly for specialty AC welding (such as thin-gauge aluminum and material less than 0.060 inch) and DC welding, either electrode negative or straight polarity, on carbon steel, stainless steel, nickel, and titanium. Item Name: Tungsten Electrodes Material: Thorium Tungsten Color: Red Tip Welding Current: 15A-500A Type: Thoriated Tungsten Electrode Specifications: Diameter: 1.6/2.0/2.4/3.0/3.2mm Features: Longevity, Easy to Use, No Radiation Size Details: Length: 175mm/6.89" (Approx.) Compare Compare Items. Thoriated Tungsten Electrodes 2% Thoriated Tungsten contains a nominal 2 wt-% or thorium oxide (ThO2) that is evenly dispersed throughout the entire length of the Tungsten. Tungsten yttrium electrodes are electrodes made of tungsten and yttrium. The external hazard estimated for a welder holding an electrode for a whole year is a very small fraction of the maximum permissible radiation dose and it is concluded that the external radiation hazard is likely to be negligible. Effects of Tungsten Addition on the Microstructure and Corrosion Resistance of Fe-3.5B Alloy in Liquid Zinc. Lanthanum, cerium, yttrium and zirconium oxides can all be used with tungsten. Thoriated Tungsten Electrodes 2% Thoriated Tungsten contains a nominal 2 wt-% or thorium oxide (ThO2) that is evenly dispersed throughout the entire length of the Tungsten. Keeping records of the amount of thoriated tungsten in store, and the numbers of electrodes issued to each welder. They are the most commonly used electrodes today and are preferred for their longevity and ease of use. 20363 Add to cart. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. National Structural Integrity Research Centre, Granta Park, Great Abington, Cambridge, CB21 6AL, UK, FAQ: The use of thoriated tungsten electrodes. It lasts the longest, holds the sharpest point, and has the strongest arc. Type of materials for welding.
