GRIDUCT 118M

CLASSIFICATION : AWS : E 11018M IS: E76BM329Fe DIN : 8529-81~ EY 6977 Mn2NiMoBH5 BS : 2493-85 2NiMOB

DESCRIPTION :

A basic coated Hydrogen controlled Low-alloy, High Tensile Electrode. The weld metal combines very high strength properties with good fracture toughness at temperature down to minus 51°C.

APPLICABLE FOR :

Specially recommended for welding ASTM A517 Gr F Q&T steel. Excellent for welding fully killed fine grained steels. The electrode works in all position gives very little spatter with an easily removable slag leaving a bead of nice appearance. The electrodes should be redried at 350 – 400° C for 2 hours to obtain better result.

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 below 120° C.

TYPICAL USES : Penstock, earth moving equipments and heavy steel Fabrications made from high tensile steel. For welding USS -T1 steel, WEL -TEN 80 steels, SA 517 grade F and their equivalents.

DIFFUSIBLE HYDROGEN CONTENT : 2.0ml/100g of deposited weld metal (Typical) IN THE WELD METAL
