The electrode 6010 is associated with which F number for the root pass?

• A. F3
• B. F4
• C. F2
• D. F5

Answer: (A)

F-numbers group electrodes by the welding procedure they support, especially for the root pass in pipe joints. For the cellulose-coated, fast-freeze electrode used to establish the root bead, the corresponding group is F3. This classification matches its deep penetration and reliable, easy-to-control root bead, which is exactly what you need for a clean and solid root pass. Other F-number groups correspond to different electrode families and performance traits, so they wouldn’t be the right match for this electrode’s root-pass needs.
