1. MANUFACTURERS OF A DIVERSE RANGE OF ADVANCED WELDING CONSUMABLES SECTION 8 NS-18.15.3 LMnR RUTILE FLUX COATED ELECTRODE WITH VERY LOW LEVELS OF SILICIOUS MINERALS THAT DEPOSITS A FERRITE-FREE AUSTENITIC WELD METAL DATA SHEET NO. 99 SPECIFICATION BS EN 1600 CLASSIFICATION E 18 15 3 L R PRODUCT DESCRIPTION Manufactured on a near matching alloy core wire, the rutile low silicious flux has a significant level of chemically basic chemicals that ensures a high purity weld metal with a refined microstructure. The flux is extruded on to the core wire using a blend of silicates that ensures both coating strength and a coating resistant to subsequent moisture absorption . WELDING FEATURES OF THE ELECTRODE The electrode performs best on DC+ but may be used AC. The arc is stable but should be used with a short arc technique rather than contact welding. The medium viscous slag is readily detachable even in deep V's. Vertical up welding is possible with 3.2mm diameter electrodes. Fillet welds have a convex profile. APPLICATIONS AND MATERIALS TO BE WELDED For welding stainless steels when totally non-magnetic weld metal is required (mainly military applications). Also for welding: Stainless steels when good toughness is required down to and lower than -196 º C. Modified 316L stainless steel as it has excellent resistance to corrosion against concentrated nitric acids and may be used to clad C-Mn steels to provide corrosion resistant overlays.
