1. MANUFACTURERS OF A DIVERSE RANGE OF ADVANCED WELDING CONSUMABLES SECTION 7 NC-200 A CHEMICALLY BASIC FLUX COATED MMA ELECTRODE FOR WELDING ALL PURE AND COMMERCIAL GRADES OF NICKEL DATA SHEET NO. 84 SPECIFICATION AWS A5.11 BS EN ISO 14172 JIS Z 3224 CLASSIFICATION ENi-1 E Ni 2061 DNi-1 PRODUCT DESCRIPTION The chemically basic flux is balanced with a controlled rutile content to ensure a fluid slag with a moderate solidification plus pure titanium as a vigorous de- oxidant and de-nitrider. The core wire is pure nickel and the weld metal a nominal 98% Ni - 2%Ti. WELDING FEATURES OF THE ELECTRODE The electrode is suitable for use on DC+ only. The slag fluidity and solidification range ensures excellent positional welding while the use of titanium ensures weld metal refinement and freedom from porosity. Metal recovery is some 1 00% with respect to the weight of the core wire. APPLICATIONS AND MATERIALS TO BE WELDED For welding nickel to itself. Typical grades include : ASTM - ASME UNS N02200 and N02201. Proprietary alloys include : Nickel 200 and 201 (special metals) Nickel 99.6 and 99.2 (UDM) The above are used for both site and workshop fabrication of chemical plant and pipework involved in alkali storage, chlorination, salt production, or caustic soda evaporation.
