Tungsten Electrode

Product Details:

Zirconiated Tungsten Electrodes (WZr) are a type of non-consumable electrode used mainly in TIG (GTAW) welding, especially for AC welding of aluminum and magnesium. 
Its current-carrying capability is equal to or greater than that of thoriated tungsten. Under no circumstances is zirconiated recommended for DC welding.

• Excellent arc stability on AC
• High resistance to contamination
• Very good current-carrying capacity
• Maintains a clean, balled tip without splitting
• Low tungsten spitting, even at high amperage

Product Details:

Copper Tungsten is a mixture of copper and tungsten. As copper and tungsten are not mutually soluble, the material is composed of distinct particles of one metal dispersed in a matrix of the other one. The micro structure is therefore rather a metal matrix composite instead of a true alloy. The material combines the properties of both metals, resulting in a material that is heat-resistant, ablation-resistant, highly thermally and electrically conductive, and easy to machine.Parts are made from the CuW composite by pressing the tungsten particles into the desired shape, sintering the compacted part, then infiltrating with molten copper. Sheets, rods, and bars of the composite mixture are available as well.

Tungsten is a rare, heavy, greyish-white transition metal with the highest melting point of all metals. It's also known as Wolfram.

Physical Properties:

• Melting point: Tungsten has the highest melting point of all metals.
• Tensile strength: Tungsten is very hard and has high tensile strength.
• Density: Tungsten is very dense and heavy.
• Heat resistance: Tungsten is heat resistant and has excellent high temperature strength.
• Radiation shielding: Tungsten can shield against radiation.
• Corrosion resistance: Tungsten is resistant to corrosion and is acid and chemical proof.

Product Details:

Tungsten Copper (WCu) Electrodes combine the high-temperature strength of tungsten with the conductivity of copper, delivering excellent arc stability, minimal wear and long service life. Ideal for precision welding applications, they provide reliable performance in high-heat, high-duty environments.

Product Details:

Thoriated Tungsten Electrodes known for their excellent arc stability, long lifespan, and ease of use in DC applications. It contains a minimum of 97.30 percent tungsten and 1.7% to 2.2% thorium oxide (thoria), which is evenly dispersed throughout the tungsten.

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. Compared with other electrodes, thoriated electrodes deposit less tungsten into the weld puddle, so they cause less weld contamination.

Note: Thorium is radioactive; therefore, you must always follow the manufacturer's warnings, instructions and the Material Safety Data Sheet (MSDS) for its use.

Product Details:

Ceriated tungsten electrodes (AWS classification EWCe-2) contain a minimum of 97.30 percent tungsten and 1.80 to 2.20 percent cerium and are referred to as 2 percent ceriated. These electrodes perform best in DC welding at low current settings but can be used proficiently in AC processes. With its excellent arc starts at low amperage, ceriated tungsten has become popular in such applications as orbital tube and pipe fabricating, thin sheet metal work, and jobs involving small and delicate parts. Like  it is best used to weld carbon steel, stainless steel, nickel alloys, and titanium, and in some cases it can replace 2 percent thoriated electrodes. Ceriated tungsten has slightly different electrical characteristics than , but most welders can't tell the difference.

Using ceriated electrodes at higher amperage is not recommended because higher amperage cause the oxides to migrate quickly to the heat at the tip, removing the oxide content and nullifying its process benefits.

Product Details:

Pure tungsten electrodes (AWS classification EWP) contain 99.95 percent tungsten, have the highest consumption rate of all electrodes, and typically are less expensive than their alloyed counterparts.

These electrodes form a clean, balled tip when heated and provide great arc stability for AC welding with a balanced wave. Pure tungsten also provides good arc stability for AC sine wave welding, especially on aluminum and magnesium. It is not typically used for DC welding because it does not provide the strong arc starts associated with Thoriated or Ceriated electrodes.

Product Details:

Molybdenum Rods serve as high-performance electrode materials for welding applications that demand extreme heat and strength. With exceptional heat resistance, low thermal expansion and a very high melting point, they are ideal for TIG welding exotic alloys, furnace welds, and joints exposed to severe temperatures. Their stability ensures consistent arc performance, minimal distortion and long service life in the most demanding welding environments.

Product Details:

Tungsten bars are used where extreme heat, strength and wear resistance are required. Common applications include high-temperature furnace components, radiation shielding, aerospace parts, electrical contacts, die casting tools and heavy-duty machining equipment. Their very high melting point, density and durability make them ideal for demanding industrial, military, and scientific applications.
