BASIC FLUX COATED ELECTRODE DEPOSITING A NICKEL BASED ALLOY WITH A HIGH CHROME CONTENT AND LOWER BUT SIGNIFICANT LEVELS OF OTHER SPECIAL ELEMENTS
NCF
CLASSIFICATION
AWS A5.11 ENiCrFe-3 | BS EN ISO 14172 E Ni 6182 | JIS Z 3224 DNiCrFe–3
PRODUCT DESCRIPTION
The chemically basic flux is extruded onto a pure nickel core wire. The flux contains chrome & iron also other remaining alloying elements together with alloys for deoxidation and grain refinement. 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
May be used for welding a wide range of nickel based alloys operating between -196 to about 480 ºC, including INCONELTM 600, INCONELTM 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 steels to each other or to nickel based alloys.
WELDING AMPERAGE AC and DC
OTHER DATA
Electrodes that have become damp should be re-dried at 180oC for 30 mins.
