Cerium Tungsten Tig Electrodes WC20 Welding Electrodes Grey Tungsten Electrode

Product Specification

Grey Head Tungsten Electrode (WC20/EWCe-2) – 2% Ceriated Tungsten Needle for TIG Welding

Product Summary

Our full‑series tungsten electrodes include Red Head (WT20), Grey Head (WC20), Blue Head (WL20), Gold Head (WL15), Green Head (WP) and White Head (WZ08). Made of high‑purity tungsten mixed with rare‑earth oxides through powder metallurgy, rolling, grinding and polishing processes, they are core welding consumables for TIG welding. Featuring stable arc ignition, low ablation rate and long service life, our multi‑type electrodes meet global welding standards and satisfy different current and material welding requirements.

Overview

Key Features (Properties)

• Non-Radioactive & Eco-Friendly: Contains no thorium; safe for operators and compliant with global environmental standards.
• Easy Arc Starting & Re-Ignition: Low electron emission work function ensures quick, consistent arc starts even at low DC currents.
• Superior Arc Stability: Stable arc with no wandering or spitting; precise heat control for clean weld beads.
• High Chemical Stability: Resists oxidation and contamination; maintains tip shape longer for consistent performance.
• Low Erosion & Long Service Life: Reduced burn-off rate extends lifespan compared to pure tungsten (WP/green).
• Versatile Current Range: Optimized for 5–250A DC; works with most inverter TIG welders.

Applications (Uses)

• Carbon steel / Mild steel
• Stainless steel (304/316, etc.)
• Copper & copper alloys (bronze, silicon bronze)
• Titanium & nickel alloys
• Thin sheets (0.5–4mm) & precision parts
• Pipe fabrication, automotive, aerospace, and general metalworking
• 

Specifications (Standard Sizes)

• Custom lengths available upon request.
• Packaging: Vacuum-sealed (10pcs/tube, 5/10 tubes/box) to prevent oxidation during storage.

Advantages

1. Safety First: Non-radioactive cerium oxide replacement for thorium; eliminates health risks and regulatory concerns.
2. Cost-Effective: Longer life and less downtime vs. pure tungsten; lower total cost than thoriated (red) electrodes.
3. Precision Welding: Ideal for thin materials and tight tolerances; minimal heat input reduces distortion.
4. User-Friendly: Easy to use for beginners; reliable re-ignition for tack welds and intermittent work.
5. Global Compliance: Meets ISO 6848, AWS A5.12, and CE standards; suitable for export worldwide.
