In the E71T-1 electrode designation, what does the 1 represent?

• A. Position (0= flat and horizontal fillet, 1= all position welding)
• B. Welding speed rating
• C. Electrode diameter
• D. Core type

Answer: (A)

The trailing digit in an electrode designation indicates the welding position capability. A value of 1 means the electrode is suitable for all-position welding, so you can weld in flat, horizontal, vertical, and overhead positions. This is what makes E71T-1 versatile for joints that aren’t always horizontal. The other options don’t fit because welding speed rating isn’t encoded in this digit, electrode diameter isn’t indicated by the trailing digit, and the core type is shown by the T (tubular flux-cored) part of the designation rather than by this final number.
