WC20 Cerium Tungsten Electrode
WC20 Cerium Tungsten Electrode Description
We use high purity tungsten powder and a small amount of cerium oxide as raw materials, and then mix, dry and reduce treatment, and then press forming, high temperature sintering, cutting and rolling, surface treatment and comprehensive quality inspection to make a complete finished product before packaging and shipping.
Features
- Strong electron emission ability, good arc starting ability, stable arc, and high welding quality.
- It has a high melting point, good thermal conductivity, and excellent high-temperature resistance. It can withstand high temperatures and is not easy to melt or deform.
- Compared with thorium tungsten electrode, it has lower radioactivity, safety and environmental protection, and a longer service life.
- Good chemical stability, good processing performance, wide range of applications.
Application
WC20 Cerium Tungsten Electrode is a kind of universal electrode, suitable for DC or AC welding, mainly used for welding carbon steel, stainless steel, alloy steel and other metal materials, and can also be used for welding pipes, micro electronic components, integrated circuit packaging, etc.
The electrode is suitable for TIG welding, manual arc welding, plasma welding, electron beam welding and other welding processes. Of course, they can also be used as cathode materials for electronic tubes, which can work stably in a high vacuum environment and emit enough electrons to ensure the normal operation of the tube.
