WELDING ELECTRODES AWS E7018

AWS A5.1-2004  E7018                 
Diameter × Length (mm)

2.5 × 300, 3.2 × 350,

4.0 × 400, 5.0 × 400
Package:20kg. Carton

E7018 is an iron powder low-hydrogen type electrode for all-position welding of mild and low alloy steels. The easily controlled arc of E7018 makes it easy to use on DC polarity.
E7018 offers excellent mechanical properties, high efficiency and high impact values at -30°C. It is also easy to strike and restrike.

ADVANTAGE                          

• 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 ISO 9001 requirements

REDRYING                            

All controlled hydrogen electrodes will perform optimally when they are dry. Unopened Hero'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.

WELDING POSITIONS

ALL POSITION

TYPICAL APPLICATION                     

E7018 is a multi-purpose electrode with excellent operator appeal. E7018 is excellent for welding of mild and low alloy steel, which is used for bridges, buildings, ship building, pressure vessels, etc. E7018 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
ABS: 3YH10
LR: 3YH15

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.
