Which electrode is a fast-fill type?

• A. E7010
• B. E7024
• C. E6010
• D. E6011

Answer: (B)

Fast-fill electrodes are designed to deposit a lot of weld metal in each pass, speeding up the build-up of the joint. The electrode that fits this description is the high-deposition type often designated as 7024. It uses an iron powder core and a coating that allows for a broad, smooth bead, making it ideal for flat and horizontal welds where you want to fill quickly with fewer passes. The other electrodes listed are chosen for deep penetration and root passes rather than rapid fill. They produce narrower beads and require more passes to achieve the full weld, which is why they aren’t considered fast-fill types.
