RATNA 8018 W (AWS A5.5 E 8018 W2)

Hydrogen Controlled Low Alloy Steel Electrode for Weathering Steels

Classification:

AWS/SFA-5.5: E 8018 W2
IS-1395: E 55BG 126Fe

Characteristics:

A hydrogen controlled, basic coated electrode for welding weathering steels. Weld metal exhibits high resistance to atmospheric corrosion, very low diffusible hydrogen, and radiographic-quality welds.

Application:

Welding of weathering steels such as SAILCOR-A & CORTEN A & B, and equivalents.
Medium tensile corrosion-resistant structural steels.
Welding of high tensile steels.

Re-Dry Condition:

Re-dry the electrode at 300°C for 1 hour before use.
