Which statement describes the relationship between 7018 and 6010?

• A. They are the same rod with different flux
• B. They are different rods with the same flux
• C. They are both for aluminum
• D. They cannot be used in GTAW

Answer: (A)

7018 and 6010 are both SMAW carbon steel electrodes, but they are different rods because their flux coatings and resulting welding characteristics differ. The numbers describe different properties: 7018 is a low-hydrogen, high-strength electrode that yields a smooth, ductile weld, while 6010 uses a cellulose sodium flux that provides deep penetration and a fast-freeze slag, making it ideal for root passes. The flux coatings are different, so the arc behavior, slag, and weld metal chemistry aren’t the same. They aren’t aluminum electrodes, and they’re used for SMAW rather than GTAW.
