Rare earth tungsten electrodes are mainly classified into the following categories according to different characteristics and application fields:
- Cerium tungsten electrode: Cerium tungsten electrode is a common rare earth tungsten electrode, which has a gray color code. Cerium tungsten electrode has the characteristics of no radiation, low combustion rate, low evaporation rate and long welding life, so it is particularly suitable for use in situations where radiation needs to be avoided. Cerium tungsten electrodes can replace radioactive thorium tungsten electrodes and are suitable for direct current or alternating current welding. They have good welding effects on carbon steel, silicon copper, titanium and other materials.
- Lanthanum tungsten electrode: Lanthanum tungsten electrode is also a common rare earth tungsten electrode. It has black, golden and sky blue coating color codes. Lanthanum tungsten electrode has good physical and chemical properties, such as easy arcing at low current, good arc column stability, good ductility and creep resistance, etc. Therefore, lanthanum tungsten electrodes are suitable for AC welding and have good welding effects on stainless steel, aluminum alloys, nickel-based alloys and other materials.
- Yttrium tungsten electrode: Yttrium tungsten electrode is a high-performance rare earth tungsten electrode with a blue color code. Due to its characteristics of good arc starting performance, high arc column stability and low burnout rate, it is particularly suitable for welding parts in high-tech fields such as military and aerospace.
In addition, according to different usage conditions and requirements, rare earth tungsten electrodes can also be divided into standard and non-standard types. Standard electrodes are suitable for general welding conditions, while non-standard electrodes are optimized for specific materials or specific process conditions.
In general, rare earth tungsten electrode is a high-temperature material with excellent properties and has broad application prospects in electron beam melting, AC arc melting and other fields. Different types of rare earth tungsten electrodes have different characteristics and application fields. Choosing the appropriate electrode type can greatly improve welding efficiency and product quality.
