Working with E6013-AW
Is E6013 easy to machine?
Deposit machines like plain low-carbon steel but grind or chip all slag first — trapped rutile slag is abrasive and dulls tools.
Can E6013 be welded?
AC or DC either polarity, all positions; short arc, drag technique, 60–100 A for φ3.2 mm; not a low-hydrogen electrode, so preheat/limit thickness on restrained or higher-carbon joints.
Can E6013 be formed, bent or molded?
Deposit is ductile (≈25 % elongation) and tolerates light straightening/peening, but shallow penetration means multi-pass on thicker sections rather than cold forming of weldments.
What surface finishes work on E6013?
Weld metal rusts like mild steel — wire-brush, remove slag fully, then prime/paint, phosphate or hot-dip galvanize; not suitable for anodizing.

E6013-AW — frequently asked
What is E6013-AW used for?
E6013-AW is typically used for light fabrication, sheet metal welding, DIY/maintenance welding and thin-gauge steel. In short: easiest-striking stick electrode; best on thin-gauge steel; all-position, shallow penetration.
What is the yield strength of E6013-AW?
E6013-AW has a typical yield strength of 400 MPa (58 ksi) and a tensile strength of 490 MPa (71.1 ksi) — weaker than 60% of steel grades. Strength varies by condition: see the 2 listed tempers.
Is E6013-AW easy to machine?
Reasonably — machinability is rated good (60/100, better than 83% of steel grades). Deposit machines like plain low-carbon steel but grind or chip all slag first — trapped rutile slag is abrasive and dulls tools.
Can E6013-AW be welded?
Yes — weldability is rated excellent (95/100). AC or DC either polarity, all positions; short arc, drag technique, 60–100 A for φ3.2 mm; not a low-hydrogen electrode, so preheat/limit thickness on restrained or higher-carbon joints.
What surface finishes work on E6013-AW?
Weld metal rusts like mild steel — wire-brush, remove slag fully, then prime/paint, phosphate or hot-dip galvanize; not suitable for anodizing.
Can E6013-AW be formed, bent or molded?
Deposit is ductile (≈25 % elongation) and tolerates light straightening/peening, but shallow penetration means multi-pass on thicker sections rather than cold forming of weldments.
What is the maximum service temperature of E6013-AW?
E6013-AW is rated for continuous use to about 350°C (662 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between E6013-AW and E6013-SR?
AW is the default condition — default condition: properties of the all-weld-metal deposit tested in the as-welded state per AWS A5.1 / GB/T 5117. SR: choose when the fabrication is PWHT'd for dimensional stability or hydrogen removal: strength drops slightly, ductility and toughness improve. Yield strength is 400 MPa in AW versus 370 MPa in SR.
