Description: AFM E8018-B2 is a low hydrogen electrode that may be used with AC or DC reverse polarity. It is different from ˇ°fast freezeˇ± electrodes in that the weld metal freezes quite rapidly even though the slag is relatively fluid.
Applications: AFM E8018-B2 is used for the welding of 1/2% Cr-1/2% Mo, 1% Cr-1/2% Mo, and 1 1/4% Cr-1/2% Mo steels. It is used to weld A355-P11 Pipe and A387 Fr. 11 Plate. Common applications include boiler steam pipes in power plants, oil refining equipment, ships and chemical plants.
