Products Description

As a professional TIG tungsten electrode manufacturer in China. Our tungsten electrode is widely used in daily glass melting, optical glass melting, thermal insulation materials, glass fiber, rare earth industry and other fields. Tungsten electrode has advantages in arc striking performance with high arc column stability and low electrode loss rate.

The tungsten electrode used in argon arc welding (TIG welding) is a key material in the welding process. Its selection directly affects arc stability, welding quality and efficiency.

The tungsten electrodes can be alloyed with a variety of metals. Different types and sizes of electrodes are used for different types of welds and materials, and welders develop preferences based on welding style and project. Certain electrode types perform better with alternating current (AC) as opposed to direct current (DC).

2% Lanthanated (Blue): The blue lanthanated electrodes are popular due to the relative ease of striking an arc and lower amperage required. They perform exceptionally well in both AC & DC applications and are a popular general use electrode. Blue electrodes are effective for welding aluminum alloys, magnesium alloys, nickel alloys, copper alloys, titanium alloys, low-alloyed steels, and non-corroding steels.

Thoriated (Red): The red thoriated type is America's favorite electrode for a reason. Extremely long lasting and highly durable, these electrodes are a staple in DC welding applications. These red electrodes are best for copper alloys, nickel alloys, titanium alloys, and non-corroding steels.

Rare Earth Mix (Purple): The innovative Rare Earth Mix electrode is an excellent substitute for the traditionally favored red thoriated type and boasts the same high-performance properties. It's best used when welding Aluminum alloys, magnesium alloys, titanium alloys, nickel alloys, copper alloys, low-alloyed steels, and non-corrosive steels.

Ceriated (Grey): Grey ceriated electrodes are popular due to their extreme ease of striking an arc with lower amperages, and their extraordinary performance with regard to DC welding applications. They perform best with titanium alloys, copper alloys, magnesium alloys, aluminum alloys, nickel alloys, non-corroding steels, and low-alloyed steels.

Zirconiated (White): White zirconiated tungsten electrodes handle higher amperage levels and work well with both transformer and inverter power sources, making them an excellent alternative to the green pure tungsten electrodes for magnesium and aluminum alloys.

Pure Tungsten (Green): The original green pure tungsten electrode contains at least 99.5% tungsten and delivers all of the properties classically associated with tungsten – superior conductivity, durability, and performance. Green electrodes are perfect for weld projects containing magnesium alloys or aluminum alloys.

1.5% Lanthanated (Gold): The gold lanthanated tungsten electrodes contain less lanthanum than their blue counterparts and are best used in DC applications. They are best for welds with titanium alloys, copper alloys, nickel alloys, and non-corroding steel.

Type and Size

Tungsten electrode is widely applied in daily glass melting, optical glass melting, thermal insulation materials, glass fiber, rare earth industry and other fields. The diameter of tungsten electrode ranges from 0.25mm to 6.4mm. The most commonly used diameters are 1.0mm, 1.6mm, 2.4mm and 3.2mm. Standard length range of tungsten electrode is 75-600mm. We can produce tungsten electrode with supplied drawings from the customers.
