Quick guide: how to read the table

The AWS electrode code carries key info: the first two digits indicate minimum tensile strength in ksi, the third digit indicates the positions allowed, and the fourth digit encodes coating and current characteristics; this coding is summarized in public references on SMAW nomenclature (Wikipedia, consulted 04/09/2026).

Coating type affects penetration and handling: cellulosic coatings give deep penetration and suit dirty or open-root work, rutile types give a smooth arc and good appearance, and iron-powder coatings boost deposition for production work; low-hydrogen fluxes limit diffusible hydrogen to reduce cracking risk (Wikipedia, consulted 04/09/2026; WeldGuru, consulted 04/09/2026).

This page gives comparative guidance only. Job-specific welding procedure specifications (WPS) and quality control are required for critical or certified work; consult applicable codes and project documents (AWS D1.1 reference, consulted 04/09/2026).

E6010

E6010 is a cellulosic electrode characterized by deep penetration and a forceful arc, useful on open-root joints and contaminated or painted surfaces where forgiveness to surface condition is needed (WeldIndex, consulted 04/09/2026).

  • Positions: designed for all-position welding.
  • Current/polarity: typically DCEN/DCEP for best arc action.
  • Penetration/deposition: deep penetration, narrow weld bead.
  • Slag/finish: cellulosic flux produces heavier slag; operator skill affects bead shape.
  • Applications: open-root pipe, field joints, repair on dirty metal.
  • Warnings: cellulosic rods require operator control; not ideal for appearance-critical thin work (WeldIndex, consulted 04/09/2026).

E6011

E6011 offers penetration similar to E6010 but is formulated to run on AC power; it is commonly selected where only AC supply is available and where metal condition is poor (Welders Supply chart, consulted 04/09/2026).

  • Positions: all-position capable.
  • Current/polarity: AC-capable; behaves like E6010 in penetration.
  • Penetration/deposition: deep penetration suitable for root passes and dirty surfaces.
  • Applications: field repair, farm equipment repair, maintenance with AC welders.
  • Warnings: cellulosic characteristics mean wetter flux and more hydrogen potential if poorly handled (Welders Supply, consulted 04/09/2026).

E6013

E6013 is a rutile-type or fast-freeze electrode favored for clean, thin mild steel work where appearance and ease of use matter; it runs smoothly and is forgiving for hobbyists and light fabrication (WeldFabWorld, consulted 04/09/2026).

  • Positions: all-position friendly, suited to vertical and overhead thin work.
  • Current/polarity: runs on AC or DC with stable arc.
  • Penetration/deposition: moderate penetration, good control on thin sections.
  • Applications: thin-sheet fabrication, appearance welds, general-purpose shop work.
  • Warnings: not ideal for heavily contaminated surfaces or heavy structural joints (WeldFabWorld, consulted 04/09/2026).

E7018

E7018 is a low-hydrogen electrode family widely specified where higher strength and low diffusible hydrogen are required; it is commonly used in structural welding when codes call for low-hydrogen filler metal and dry storage practices (WeldIndex, consulted 04/09/2026).

  • Positions: designed for all-position work with sound technique.
  • Current/polarity: typically DC; check manufacturer guidance.
  • Penetration/deposition: good fusion with controlled hydrogen levels.
  • Applications: structural steel welding where code compliance is required.
  • Warnings: must be stored dry; moisture in flux increases hydrogen and cracking risk; many codes reference low-hydrogen practice (WeldIndex, consulted 04/09/2026).

E7024

E7024 is an iron-powder, high-deposition drag rod intended for flat and horizontal production welding where fill rate matters; it is not intended for out-of-position work (WeldGuru, consulted 04/09/2026).

  • Positions: flat and horizontal only.
  • Current/polarity: tolerant of AC and DC per product specifics.
  • Penetration/deposition: high deposition for fast fillet fills.
  • Applications: production fillets, long runs on flat plate.
  • Warnings: not for vertical or overhead; avoid for thin-gauge appearance work (WeldGuru, consulted 04/09/2026).

E308L, E309L, E316L (stainless families)

Stainless stick electrodes should be matched to base alloy and service: E308L is appropriate for 304-type stainless, E316L for 316 service, and E309L can bridge stainless-to-carbon transitions or higher-dilution scenarios (Hobart catalog, consulted 04/09/2026; Voestalpine product listings, consulted 04/09/2026).

  • Positions/current: product-dependent; consult manufacturer datasheet.
  • Applications: E308L for 304/308L stainless-to-stainless; E309L for dissimilar joints; E316L for 316 service environments.
  • Warnings: select filler chemistry to match corrosion and thermal requirements; consult manufacturer tech data (Hobart, consulted 04/09/2026).

Mild carbon steel

For clean, thin mild carbon plate where appearance matters, rutile E6013 is typically suitable; for production flat fillets where deposition rate matters, E7024 is often used; for contaminated or open-root situations E6010 or E6011 is typically chosen depending on available power source (WeldFabWorld, consulted 04/09/2026; WeldGuru, consulted 04/09/2026).

Low-alloy / high-strength steels

Where higher tensile strength and control of hydrogen are required for structural applications, low-hydrogen electrodes in the E7018 family are commonly specified and are often referenced by codes for critical work; storage and handling practices must control moisture to limit hydrogen-induced cracking (WeldIndex, consulted 04/09/2026; AWS D1.1 reference, consulted 04/09/2026).

Stainless steels

Select stainless filler to match base metallurgy: E308L for 304/308L base metal, E316L for 316 base, and E309L when joining stainless to carbon steel or when higher dilution tolerance is needed; consult manufacturer catalogs for exact product designations and mechanical/chemical limits (Hobart catalog, consulted 04/09/2026; Voestalpine, consulted 04/09/2026).

Repair and field work on contaminated surfaces

Cellulosic electrodes (E6010, E6011) are typically chosen for field repairs on rusty, painted, or oily surfaces because of deep penetration and arc force; E6011 is used where only AC is available, while E6010 is used when DC power and operator skill are available (WeldIndex, consulted 04/09/2026; Welders Supply, consulted 04/09/2026).

Which electrode for which user/profile

Recommendations are conditional and meant as comparative guidance; project WPS and code requirements must govern final selection.

  • Maintenance/field repair with an AC welder and dirty metal: E6011 is typically suitable because it runs on AC and tolerates surface contamination; E6010 may be suitable if DC is available and the operator is experienced (Welders Supply, consulted 04/09/2026).
  • Structural, code-controlled welds on carbon or low-alloy steel: E7018-family low-hydrogen electrodes are typically chosen where codes reference low-H filler metal; ensure dry storage and follow applicable code/WPS requirements (WeldIndex, consulted 04/09/2026; AWS D1.1, consulted 04/09/2026).
  • Fast production flat fillets on clean plate: E7024 is typically chosen for high deposition and fill rate in flat/horizontal positions (WeldGuru, consulted 04/09/2026).
  • Thin-sheet appearance work or hobbyist welding: E6013 is typically recommended for smooth arc and ease of slag removal (WeldFabWorld, consulted 04/09/2026).
  • Welding stainless-to-stainless (304/308): E308L is typically appropriate; for stainless-to-carbon transitions, E309L is often used to bridge metallurgy (Hobart, consulted 04/09/2026).

Practical notes, storage, and testing

  • Low-hydrogen electrodes must be kept dry; moisture in flux raises diffusible hydrogen and increases cracking risk — follow manufacturer storage recommendations and bake rods if required by the supplier (WeldIndex, consulted 04/09/2026).
  • Check electrode packaging and lot notes on manufacturer datasheets for position and current guidance before use (Hobart catalog, consulted 04/09/2026).
  • Perform test welds and nondestructive or destructive testing as required by code and project WPS; this page does not substitute for project-specific procedure or code compliance (AWS D1.1 reference, consulted 04/09/2026).
