2% thoriated tungsten electrodes
These 2% thoriated tungsten electrodes, designated EWTh-2, are a non-consumable electrode used in Gas Tungsten Arc Welding (GTAW/TIG). They are manufactured from a tungsten matrix containing approximately 2% thorium oxide (ThO2) by weight. Classified under AWS A5.12, they are recognized for providing superior arc stability and electron emission, particularly in DC welding applications.
The 2% thorium oxide addition lowers the electrode's electron work function, allowing it to operate at a temperature well below its melting point and maintain a stable, focused arc. This makes them a benchmark for welding carbon steel, stainless steel, and nickel alloys. While they are the global market share leader in tungsten electrodes, their use is regulated in some regions due to the low-level radioactivity of thorium, which primarily emits alpha particles. Alternatives like ceriated or lanthanated electrodes are often used where this is a concern.
These electrodes are typically supplied in standard lengths of 150mm and 175mm, with diameters ranging from 1.0mm to 6.4mm, packaged in sets of 10 pieces. They are widely used in aerospace, automotive, and precision fabrication industries. Buyers should contact Beijing Sunstone Tungsten & Molybdenum Co., Ltd. to confirm available diameters, custom lengths, and bulk packaging options for their specific welding operations.
| Electrode Classification | EWTh-2 (AWS A5.12) |
| Base Material | Tungsten (W) |
| Additive | 2% Thorium Oxide (ThO2) |
| Primary Welding Current | Direct Current Electrode Negative (DCEN) |
| Standard Lengths | 150mm, 175mm |
| Diameter Range | 0.5mm to 12mm (typical range 1.0-6.4mm) |
| Standard Packaging | 10 pieces per box |
| Typical Tip Preparation | Ground to a truncated cone or balled for AC (though not recommended) |
| Typical Current Capacity (3.2mm dia.) | 220-350A (DCEN) |
| Typical Electron Work Function | Lowered by ThO2 addition, improving arc starting |
Beijing Sunstone Tungsten & Molybdenum Co., Ltd. is a supplier located in the Shilong Development Zone, Mentougou District, Beijing, China. The company's name and product focus indicate a specialization in tungsten and molybdenum products, including welding electrodes. The listing does not provide details on the company's founding year, production capacity, or export history.
The supplier is categorized as an imported tier with a harbor trust tier on the platform. The recorded response rate is 0.00% with an average response time of 0 hours, meaning there is no platform-based performance data available. Potential buyers should initiate direct contact to evaluate the company's communication and service levels.
2% thoriated tungsten electrodes (EWTh-2) are classified under AWS A5.12 and represent the benchmark in non-consumable electrode performance for GTAW/TIG welding applications. Containing approximately 2% thorium oxide in a tungsten matrix, these electrodes offer superior arc stability and electron emission compared to pure tungsten alternatives, making them the preferred choice for critical welding in aerospace, automotive, and precision fabrication. As a regulated material in certain markets due to its low-level radioactivity, EWTh-2 electrodes are widely exported from China and are typically traded in standard 150mm and 175mm lengths across a full diameter range from 1.0mm to 6.4mm.

Sourcing 2% Thoriated Tungsten Electrodes from Beijing Sunstone Tungsten & Molybdenum Co., Ltd. - China Import Guide
Before importing 2% thoriated tungsten electrodes from Beijing, confirm the regulatory requirements for radioactive materials in your country. This may involve obtaining an import license from your national nuclear or radiation safety authority. Ensure the supplier can provide all necessary documentation, including Safety Data Sheets (SDS) and certificates of radioactivity, to facilitate customs clearance.
Clarify all trade and logistics terms with the supplier. Confirm the available Incoterms (e.g., FOB Beijing, CIF), lead times for production, and minimum order quantities. Since the supplier has no response history on the platform, direct communication is vital to establish reliable terms and assess their ability to meet your delivery schedule.
Implement a quality control check upon receipt. Verify that the packaging is intact and that the electrodes match the ordered diameter and length. For critical welding jobs, consider testing a sample batch for arc stability and electrode wear. Request a Certificate of Analysis for the specific material batch to confirm the thorium oxide content is within the specified 2% range.
