How to choose tungsten for welding applications




Tungsten welding rods are essential materials in metal welding, each type offering unique properties based on its color. These include gold, red, gray, and green rods, each suitable for different applications such as DC and AC welding, aluminum welding, or situations requiring stable and consistent arcs. Choosing the right welding rod ensures optimal welding performance and safety for the user.
- Gold tungsten welding wire is suitable for welding all types of metals. It can be used for both DC and AC welding. It is ideal for repetitive arc welding or PULSE welding. It produces less smoke and contains no harmful substances to health
- Red tungsten welding wire has high arc performance with a steady current release, providing a good arc start and relatively stable current compared to other tungsten welding wires. It works well for both DC and AC welding, and provides good deep penetration in the weld.
- Gray tungsten welding wire is suitable for low DC current welding. It can also be used to weld aluminum with AC current. It is ideal for welding thin materials or for automated welding
- Green tungsten welding wire is made of pure tungsten and is perfect for welding aluminum. It does not emit radiation and works well with low DC current compared to other colors. It provides a consistent arc and deep weld penetration, and there is no need to sharpen the tip during use.
