Product Features & Applications

This is a green tip pure tungsten electrode, a dedicated consumable for TIG (GTAW) welding. Made from ≥99.5% high-purity tungsten with no added elements, it offers an economical option for AC welding of aluminum and magnesium alloys. Designed for use with AC welding machines, it leverages the "cathodic cleaning" effect to remove oxide films on aluminum/magnesium surfaces, suitable for scenarios with moderate welding requirements. It is non-radioactive and safe to use.

1. Basic Product Information

The green tip pure tungsten electrode is the most basic type of electrode for TIG welding, manufactured from ≥99.5% high-purity tungsten rods with no rare earth oxide additives, resulting in the lowest cost among all tungsten electrodes. Marked with a green tip for easy identification, it is compatible with standard TIG welding machines and serves as an entry-level consumable for AC welding of aluminum and magnesium alloys.

2. Performance Characteristics and Limitations

  • Advantages: Non-radioactive and safe to use; economical cost, suitable for bulk purchasing; compatible with AC welding machines, capable of removing oxide films on aluminum/magnesium alloys.
  • Limitations: Weak electron emission, making arc initiation slightly more difficult than ceriated or lanthanated tungsten electrodes; moderate arc stability and poor anti-contamination performance, easily affected by base metal impurities during welding; prone to burn-off and tip deformation under high currents, unsuitable for long-duration high-load operations.

3. Application Scenarios and Operating Recommendations

  • Applicable Scenarios: Recommended only for AC TIG welding of aluminum, magnesium, and their alloys, suitable for scenarios with moderate welding quality requirements and stable welding conditions, such as common aluminum components and non-precision magnesium alloy parts.
  • Operating Recommendations:
    1. Must be used with an AC welding machine; not recommended for DC welding.
    2. Grind the tip to a hemispherical or slightly blunt taper to avoid arc instability caused by overly sharp tips.
    3. Use a slightly higher arc initiation current than with additive tungsten electrodes, and minimize frequent arc starts.
    4. Avoid contact with the base metal during welding to prevent electrode contamination that affects arc stability.

4. Environmental and Safety Notes

Pure tungsten electrodes contain no radioactive or rare earth additives such as thorium, cerium, or lanthanum, posing no radioactive risk and being safe for long-term use, meeting the requirements for environmentally friendly welding consumables.
