A CHEMICALLY BASIC FLUX COATED MMA ELECTRODE DEPOSITING A NICKEL BASED ALLOY HIGH IN BOTH CHROMIUM AND MOLYDENIUM
NCM-625
CLASSIFICATION
AWS A5.11 ENiCrMo-3 | BS EN ISO 14172 E Ni 6625 | JIS Z 3224 DNiCrMo-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 is suitable for use on both AC and DC+ and welds with great arc stability and thus control of the molten weld pool. Slag detachability is good. The weld beads are bright and evenly rippled with fillet welds slightly convex. Strike and re-strike should be made with the established back step technique
APPLICATIONS AND MATERIALS TO BE WELDED
Welding the following materials: ASTM / ASME UNS N06625 A494 Cu 6Mo cast. Proprietary Alloys: INCONEL 625 (Special Metals), NICROFER 6020hMo and 6022hMo (Krupp VDM). May also be used for superaustenitic alloys such as: 254SMo (Avesta), Sanicro 28 (Sandvick), Nicrofer 3127LC (Krupp VDM), Incolloy 825 (Special Metals), Nicrofer 4221 (Krupp VDM), 904L (Uddelholm) and similar. Also for 9% Ni cryogenic steels and dissimilar welds.
WELDING AMPERAGE AC and DC
OTHER DATA
Electrodes that have become damp should be re-dried at 180oC for 1 hour.
