7018 and 6010 are the same rod with different flux.

• A. True
• B. False
• C. They are different rods with the same flux
• D. They are never used in GTAW

Answer: (A)

In shielded metal arc welding, the flux coating is what defines the electrode’s behavior—how the arc shields the weld, how much hydrogen is introduced, how deep the weld penetrates, and how the bead cools and deposits. The designations 7018 and 6010 describe different electrode types with different flux chemistries and welding characteristics. A 7018 electrode is a low-hydrogen, iron-powder flux electrode that produces ductile, clean welds with relatively low hydrogen content. A 6010 electrode uses a cellulose-based flux that gives a deep-penetration arc and is desirable for root passes and rapid filling in certain positions. Because their fluxes are different, they are not the same rod with just a different flux; they are two distinct rods, each tailored for different welding requirements. Also, they are both used for shielded metal arc welding, not GTAW, which uses a tungsten electrode and shielding gas rather than flux-coated rods.
