IDENTIFICATION
Griduct 108M, E 10018M
CLASSIFICATION
AWS/SFA 5.5: E 10018M
DESCRIPTION
A basic coated hydrogen controlled low-alloy, high tensile electrode. The electrode works in all position, gives very little spatter with an easily removable slag leaving a bead of nice appearance. The deposited welds are of radiographic quality.
