Package
20kg/Carton

EASYARC™ 7018-1 is an iron powder low-hydrogen type electrode for all-position welding of mild and high strength low alloy steels. The easily controlled arc of EASYARC™ 7018-1 makes it easy to use on either DC or AC polarity.EASYARC™ 7018-1 offers excellent mechanical properties and notch toughness.

ADVANTAGE LINCOLN
  • Superb weld profiles in all positions
  • Excellent AC/DC operator appeal
  • Easy slag removal
  • Excellent mechanical and toughness properties
  • Manufactured under a quality system certified to ISO9001 requirements.
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™ 7018-1 is a multi-purpose electrode with excellent operator appeal. It is recommended for the critical welding of C-Mn, micro alloyed, and low alloy structural steels. Typical applications include the welding of offshore platforms, ship building, pressure vessels and heavy steel structure on bridges and buildings.

CONFORMANCE

AWS A5.1:E7018-1
ASME SFA-5.1

GUIDELINES FOR USE
  • If necessary, re-dry electrodes at 350-380 íŠ for 30-60 minutes before use. Exposed electrodes should be stored at 100-150íŠ.
  • All water, rust and oil should be completely removed from base material to prevent cracking and blowholes.
  • Backstep method should be applied to prevent porosity 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.
