1. MANUFACTURERS OF A DIVERSE RANGE OF ADVANCED WELDING CONSUMABLES SECTION 7 NCF 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. 88 SPECIFICATION AWS A5.11 BS EN ISO 14172 JIS Z 3224 CLASSIFICATION ENiCrFe-3 E Ni 6182 DNiCrFe–3 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 g rain refinement and the blend of silicates used during electrode production ensure b oth coating strength and resistance to subsequent moisture absorption. WELDING FEATURES OF THE ELECTRODE The electrode will weld on AC but is used to best a dvantage on DC+. The arc is stable and forceful and should be used with short a rc 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 May be used for welding a wide range of nickel base d alloys operating between - 196 to about 480 ºC, including INCONEL TM 600, INCONEL TM 601 and NIMONIC 75. The high manganese content of the alloys gives it a very high resistance to hot cracking and to dilution from nickel and iron based alloys, alloying many dissimilar welds to be made including carbon and stainless ste els to each other or to nickel based alloys.
