A CHEMICALLY BASIC FLUX COATED MMA ELECTRODE FOR WELDING CORROSION RESISTANT ALLOY
NCM-13
CLASSIFICATION
AWS A5.11 ENiCrMo-13 | BS EN ISO 14172 E Ni 6059
PRODUCT DESCRIPTION
The chemically basic flux is extruded onto a high purity nickel core wire. The flux contains the 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 both on AC and DC, and welds with great arc stability and thus control of the molten weld pool, specially on DCEP. Slag detachability is good. The weld beads are bright and evenly rippled with fillet welds slightly convex.
APPLICATIONS AND MATERIALS TO BE WELDED
For welding low-carbon nickel-chromium-molybdenum alloys, for welding the clad side of joints in steel clad with low-carbon nickel-chromium-molybdenum alloys, and for welding low carbon nickel-chromium-molybdenum alloy to steel and to other nickel base alloys. Typical alloys to be welded include alloy 59 and similar (Hastelloy C-2000, Inconel 686), alloy C-22 and similar, also superaustenitic stainless steels (654SMO, Uranus B66). Higher Cr level gives better performance than Alloy C22 on more oxidising media.

OTHER DATA
Electrodes that have become damp should be re-dried at 180oC for 1 hour.
