GRIDUCT 108M

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.

•    For welding USS-T1 steel, N-A-XTRA 63 &70, H SBB77V

WELDING PROCEDURE
Use short arc length. Weaving of electrodes, if necessary should be done at slow speed and keeping a short arc. The electrodes should be used in perfectly dry condition. Maintain interpass temperature between 100 - 140°C.

DIFFUSIBLE HYDROGEN CONTENT IN THE WELD METAL : 3.0ml / 100g of deposited weld metal, Maximum
REDRY AT : 350 - 400°C / for 2 hrs.
