In the FCAW electrode label E71T-1, what does the E represent?

• A. Electrode
• B. Erosion
• C. Energy
• D. Encapsulation

Answer: (A)

The leading letter in an FCAW wire designation identifies the item used as the filler metal for arc welding. That letter is E, which means it is an electrode. So the E represents electrode. The rest of the code (71T-1) conveys strength and the tubular flux-cored nature, but the first symbol specifically naming the consumable as an electrode is what the question asks. The other terms don’t match welding classification terminology.
