Atom Arc 7018 is an all-position low hydrogen moisture resistant electrode. The wider operating ranges and smooth weld metal transfer minimizes post weld clean up. This premium quality electrode meets a multitude of codes and welding specifications. Atom Arc 7018 was developed to weld carbon and low-alloy steels, including a variety of hardenable steelsFeaturesEasy slag removalCapable of x-ray quality and excellent impact propertiesPremium arc performanceFor welding hardenable steels, cold rolled steels, or other steels, low alloy and mild steels when stress relieving normally would be required but cannot be done, all-position welding, general fabrication, power generation, petrochemical, pressure vessels, pressure pipingFlat, horizontal, vertical up, overhead welding positionsMedium penetration2.6 lbhr at 120 amp, 2.7 lbhr at 140 amp deposition rate, 71.6% at 120 amp, 70.9% at 140 amp efficiency ESAB AtomArc 7018 255011819 Covered Electrode, Diameter: 18 Inch, Length: 14 Inch, Current Type: ACDC+, Amperage: 90 - 160 amp, Package: 50 lb Hermetically Sealed Can, AWS Class: AWS A5.1: E7018, AWS A5.1: E7018H4R, Coating: Low Hydrogen Iron Powder, Tensile Strength: 78 ksi (As Welded), Yield Strength: 68 ksi (As Welded), Elongation in 2" (%): 30% (As Welded), Charpy V-Notch: 168 ft.-lb.
