ELECTRODE FOR WELDING WEATHERING STEEL
IDENTIFICATION
Griduct 88W2, E 8018-W2
CLASSIFICATION
AWS/SFA 5.5: E 8018-W2, DIN 8529: 5043NiCuB
DESCRIPTION
A heavy coated, low-hydrogen, all-position electrode depositing weld metal having 0.5% Cr, 0.5% Ni and 0.5% Cu. The deposited weld metal exhibit improved corrosion resistance properties and therefore
recommended for welding weathering steels like Cor-Ten A, Cor-Ten B and equivalent. The weld metal also resists preferential corrosion in seawater, and has applications for welding micro-alloyed and C-Mn steels.
