Package
20kg/Carton

EASYARC™ 7018 is an iron powder low-hydrogen type electrode for all-position welding of mild and low alloy steels. The easily controlled arc of EASYARC™ 7018 makes it easy to use on DC polarity.

EASYARC™ 7018 offers excellent mechanical properties, high efficiency and high impact values at -30°C. It is also easy to strike and restrike.

ADVANTAGE LINCOLN
  • High deposition rates
  • Easy slag removal
  • Excellent crack resistance and X-ray performance
  • Flat or slightly convex beads have distinct ripples with little spatter
  • Manufactured under a quality system certified to ISO9001 requirements
  • Available in PERMAPACK™ (Vacuum Sealed)
REDRYING

All controlled hydrogen electrodes will perform optimally when they are dry. Unopened Lincoln PERMAPACK's provide excellent protection against moisture pick-up in good storage conditions. Should re-drying be necessary, remove electrodes from the packet / container and spread thinly and evenly on racks in a ventilated oven. For electrodes that have had a short or mild exposure to the atmosphere then re-drying at 572°F(300°C) for 1 hour will be sufficient. For electrodes that have been exposed to longer or more aggressive conditions or for critical work re-drying at 572-662°F (300- 350°C) for 1-2 hours is recommended. After re-drying electrodes should be stored in a hot box.

TYPICAL APPLICATION

EASYARC™ 7018 is a multi-purpose electrode with excellent operator appeal. EASYARC™ 7018 is excellent for welding of mild and low alloy steel, which is used for bridges, buildings, ship building, pressure vessels, etc. EASYARC™ 7018 can also be used for the construction or repair of earth moving, farm and mining equipment.

CONFORMANCE

AWS A5.1:E7018
ASME SFA-5.1

GUIDELINES FOR USE
  • All water, rust and oil should be completely removed from base material to prevent cracking and blowholes.
  • Backstep method should be applied to prevent blowholes and pits during starting. Arc length should be kept as short as possible during welding.
  • If weaving is required, the width should not exceed 3x the diameter of the electrode.
