1. MANUFACTURERS OF A DIVERSE RANGE OF ADVANCED WELDING CONSUMABLES SECTION 4 RD-118G LOW HYDROGEN IRON POWDER ELECTRODE FOR WELDING STEELS WITH A MINIMUM UTS OF 760 N/mm 2 DATA SHEET NO. 43A SPECIFICATION AWS A5.5 CLASSIFICATION E11018-G PRODUCT DESCRIPTION The design emphasis of the chemically basic flux is engineered to ensure the optimum weld metal properties demanded by the specification are fully met. The basic flux containing the appropriate alloying elements with a controlled balanced addition of iron power, is extruded onto a high purity ferritic core wire with a blend of silicates that ensures both coating strength and a coating resistant to subsequent moisture absorption . WELDING FEATURES OF THE ELECTRODE The chemical nature of the flux together with a significant proportion of iron powder ensures maximum deposition efficiency without detracting from its ability to be used in all positions except vertical down. Overall the arc is very stable, slag detachability is good and metal recovery is some 115% with respect to the core wire. APPLICATIONS AND MATERIALS TO BE WELDED This electrode is typically used for welding of general structural steel fabrication in high strength low-alloyed steels, which may be used for cranes, earth moving equipment, and other highly stressed structural components. However, hydrogen release heat treatment is often applied at 250 º C for 1 hour per 15cms of plate thickness and this in combination with 150 º C minimum preheat ensures the integrity of the HAZ areas.
