Thorium Tungsten Electrodes are one of the earliest rare earth tungsten electrodes used globally and are still considered the best in terms of welding performance. They have the highest market share worldwide. These electrodes are widely used in various applications due to their superior performance compared to pure tungsten and other oxide electrodes. They are irreplaceable in long-term use scenarios. Thorium Tungsten Electrodes offer easy operation, high current load capacity, stable arc starting, a larger arc gap, minimal loss, and a longer service life. They also have a high recrystallization temperature, better electrical conductivity, and excellent mechanical cutting performance. These features make them the preferred choice for welding carbon steel, stainless steel, nickel alloys, and titanium metals.

Cerium Tungsten Electrodes are environmentally friendly and do not contain radioactive materials. They are ideal for low melting rate applications and provide excellent service life under optimal welding conditions. They are also suitable for small or complex parts requiring low current welding. These electrodes combine high performance with environmental benefits.
