CLASSIFICATION
AWS A5.11 ENiCrFe-2 | EN ISO 14172 E Ni 6133 | JIS Z 3224 DNiCrFe–2
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 mostcircumstances, is easily detachable. The weld appearance is bright and fillet welds are convex.
APPLICATIONS AND MATERIALS TO BE WELDED
For welding the following materials to withstand service temperature up to 900OC: 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 -110OC. 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.
WELDING AMPERAGE AC and DC
OTHER DATA
Electrodes that have become damp should be re-dried at 180oC for 1 hour
