1. MANUFACTURERS OF A DIVERSE RANGE OF ADVANCED WELDING CONSUMABLES SECTION 7 NCO BASIC FLUX COATED ELECTRODE DEPOSITING A NICKEL BASED ALLOY WITH A HIGH CHROME CONTENT AND LOWER BUT SIGNIFICANT LEVELS OF OTHER SPECIAL ELEMENTS DATA SHEET NO. 87 SPECIFICATION AWS A5.11 BS EN ISO 14172 JIS Z 3224 CLASSIFICATION ENiCrFe-2 E Ni 6092 DNiCrFe–2 PRODUCT DESCRIPTION The chemically basic flux is extruded onto a fully alloyed core wire with respect to nickel and chromium. The flux also contains alloys for deoxidation and grain refinement and the blend of silicates used during electrode production ensure both coating strength and resistance to subsequent moisture absorption. WELDING FEATURES OF THE ELECTRODE The electrode will weld on AC but is used to best advantage on DC+. The arc is stable and forceful and should be used with short arc technique. The fluid slag lends itself to positional welding. The slag, under most circumstances, is easily detachable. The weld appearance is bright and fillet welds are convex. APPLICATIONS AND MATERIALS TO BE WELDED For welding the followin g materials to withstand service temperature up to 900 O C: INCONEL 600 INCOLOY 800 INCOLOY DS (trade names - special metals). May also be used to weld semi-cryogenic steels containing 3% - 5% nickel in service at temperature down to -110 O C. The composition of the weld metal does not match the specification of any proprietary brand of high nickel material but it is closely related to INCONEL 600. WELD METAL ANALYSIS COMPOSITION % BY Wt.
