ER70S-6 .035 inch is best described as a type of what?

• A. MIG welding wire
• B. Flux core
• C. Shielding gas
• D. Filler rod

Answer: (A)

ER70S-6 .035 inch is a solid MIG welding wire. In MIG welding, the filler metal is supplied as a continuous wire fed through the gun, and ER70S-6 is a common specification for carbon steel wire with good deoxidizers to help prevent porosity. The .035 inch refers to the wire diameter, which affects how it feeds and the weld bead it produces. This option is therefore describing the filler metal used in MIG welding. It’s not flux-core (that would typically indicate a flux-filled wire), not a shielding gas (gas is separate from the wire), and not a filler rod (that’s used in TIG or other processes).
