Red head thoriated tungsten electrode (WT20)
Currently the most stable and widely used tungsten electrode is mainly used in the welding of carbon steel, stainless steel, silicon copper, copper, bronze, titanium and other materials, but it has slight radioactive pollution.
Gray head cerium tungsten electrode (WC20)
At present, the scope of use is only second to that of thoriated tungsten electrodes, especially in the conditions of low current direct current. It is mainly used in the welding of carbon steel, stainless steel, silicon copper, copper, bronze, titanium and other materials.
Green head pure tungsten electrode (WP)
Pure tungsten electrodes do not add any rare earth oxides, and have the smallest electron emission ability, so they are only suitable for welding under high AC load conditions, such as aluminum welding.
Choice of Tungsten Tip Shape
The shape of the tip of the tungsten pole has a great influence on the stability of the arc and the shape of the weld.
Common tungsten electrode tip shapes and reasons for DC tungsten argon arc welding (tungsten electrode connected to negative electrode):
The shape and reason of the tip of the tungsten pole during AC tungsten arc welding:
