Cerium tungsten electrode is the electrode of tungsten added with 2% CeO2. It is the earliest developed non-radioactive tungsten electrode product in China. Its grade is WC20 with color sign of gray.
Cerium tungsten electrode has excellent arc starting performance under low current load condition, and the arcing current is so small that it is often applied for welding pipes, stainless steel products and parts with high precision.
The W-Ce electrode can meet the requirements of stainless steel welded pipe under high current and high load GTAW/PAW conditions. While you should also do as follows to ensure the service life of the W-Ce electrode under high current and high load GTAW/PAW conditions, and to obtain the maximum welding speed and the best quality of GTAW weld seam:
1. Properly grasp the electrode end sharpening angle and flat end diameter.
2. Set appropriate welding current, arc length, and shielding gas flow, etc.
3. Clean the stain on the joint interface of weld seam in time.
4. Pay sufficient attention to the influence of the content of surface-active elements such as S on the forming process of weld seam.
