ER705-2 electrode is associated with which welding processes?

• A. MIG and TIG
• B. SMAW and FCAW
• C. GMAW and SMAW
• D. GTAW and FCAW

Answer: (A)

ER705-2 is a filler-metal designation. The “ER” indicates electrode filler metal, and the numeric code identifies the alloy and the welding methods it’s intended for. This type of filler metal is designed for deposition by processes that add filler metal from a wire or rod, which are MIG (GMAW) and TIG (GTAW). In MIG, the filler is a continuously fed wire; in TIG, bare filler rods of the same alloy are used. This is different from SMAW, which uses coated electrodes, or FCAW, which uses flux-cored electrodes with their own classifications. So, this filler-metal designation aligns with MIG and TIG.
