An R or T in electrode classifications means?

Explanation:
An electrode’s classification often includes a letter that tells you its physical form. The R stands for Rod, meaning a solid round electrode, while the T stands for Tubular, meaning a hollow tube filled with flux (a flux‑core electrode). This distinction matters because it changes how the electrode feeds, how the arc behaves, and how shielding is produced during welding. So when you see R or T, you’re being told whether the electrode is a solid rod or a tubular flux‑core type. The other options describe shapes not used in this labeling convention.
