E8018-W2
AWS A5.5 E8018-W
ASME SFA 5.5 E8018-W
E8018-W2 electrodes are designed specifically for welding the low-alloy, high-strength “weathering” steels where corrosion resistance, toughness as well as good creep resistance properties found with base metals such as ASTM A588, A242, Cor-ten, and Mayari R®. The uniform color blend of weld deposit with “weathered” steel makes these electrodes an excellent choice when architectural appearance is important.
