Notes
- The "Standard Requirement" values are the minimum requirements specified in AWS A5.1 / GB/T 5117 for E6011 (E4311) deposited metal.
- "Typical Measured Value" comes from actual product test reports, showing that actual performance often exceeds the standard lower limits.
- Elements S and P are restricted as impurities to ensure weld toughness.
- These data can be used for welding procedure qualification and material selection.
FAQ
Q1: What type of welding electrode is E6011?
A1: E6011 is a low-carbon steel welding electrode with a cellulose potassium-type coating. It is suitable for AC or DC positive polarity (DCEP) power supplies and can be used for all-position welding.
Q2: In what applications is E6011 mainly used?
A2: It is commonly used in general manufacturing, structural engineering, pipe welding (especially thin-walled pipes), galvanized steel, shipbuilding, bridges, and railway vehicles. It also has good adaptability to surfaces with rust, oil, or slight contamination.
Q3: What are the recommended welding current and polarity?
A3: E6011 can be used with AC or DC positive polarity (DCEP). Example of commonly used current ranges: 3.2mm diameter: approximately 75–125A; 4.0mm diameter: approximately 110–165A. The actual current needs to be adjusted according to the welding position and plate thickness.
Q4: What are the differences between E6011, E6010, E6013, and E7018?
A4:
E6010 is only for DC positive polarity, producing a stronger arc and deeper penetration; E6011 is AC compatible, producing a softer arc.
E6013 has a titanium-calcium coating, resulting in a more stable arc and less spatter, suitable for thin plates, but its penetration is not as strong as E6011.
E7018 is a low-hydrogen electrode with higher strength (70ksi) and better crack resistance, but requires strict moisture protection and is generally not used on dirty surfaces.
Q5: How should E6011 be stored and protected from moisture?
A5: Cellulose coatings require a certain moisture content (approximately 3-7%) for proper operation, therefore drying is not recommended. Unused electrodes should be kept in their original packaging and stored in a dry, well-ventilated indoor environment, avoiding high temperatures or high humidity.
