How to choose the tungsten electrode correctly?

The red-headed thorium tungsten electrode is currently the most stable and most widely used tungsten electrode. It is mainly used for welding carbon steel, stainless steel, silicon copper, copper, bronze, titanium and other materials, but there is slight radioactive contamination.

Grey-head cerium-tungsten electrodes are currently used second only to thorium-tungsten electrodes, especially in low current DC conditions. Mainly used for welding carbon steel, stainless steel, silicon copper, copper, bronze, titanium and other materials.

Green-head pure tungsten electrodes are currently used less and are used in aluminum, aluminum alloys, magnesium, and magnesium alloys. They do not require high welding conditions.

White-head zirconium-tungsten electrodes are currently widely used, mainly for welding aluminum and aluminum alloys.

The golden head lanthanum tungsten electrode and the sky blue head lanthanum tungsten electrode are WL20 and WL15 respectively. They have a wide range of applications and are the most promising welding electrodes. They are used for welding aluminum and aluminum alloys as well as carbon steel, stainless steel, silicon copper, copper Welding of bronze, titanium and other materials.
