1. MANUFACTURERS OF A DIVERSE RANGE OF ADVANCED WELDING CONSUMABLES SECTION 10 BM-50 A 55 NICKEL- 45 IRON ALLOYED ELECTRODE FOR FULLY MACHINABLE CRACK- RESISTANT WELDS ON A WIDE RANGE OF CAST IRONS DATA SHEET NO. 143A SPECIFICATION AWS A5.15 EN ISO 1071 JIS Z 3252 CLASSIFICATION ENiFe-CI EC NiFe-CI DFC NiFe PRODUCT DESCRIPTION The design emphasis of the chemically basic flux assures the metallurgical integrity of the weld metal fumes. The high graphite content of the flux is expelled from the molten metal, compensating for the compression welding stresses thus preventing weld metal cracking. Special nickel-iron alloy core wire used gives extra heat-resistability of welding electrode. WELDING FEATURES OF THE ELECTRODE The arc is stable both AC and DC, but is very soft, thus minimising dilution. Weld beads are smooth, bright and evenly rippled. The slag is fairly fluid but relatively quick freezing, thus allowing smooth blends when edges are involved. The slag is readily controlable, thus making positional welding very easy, plus the slag is easily detachable. APPLICATIONS AND MATERIALS TO BE WELDED The NiFe weld metals produce higher strength welds than the pure nickel types and are thus the preferred choice for alloyed, nodular and spheroidal cast irons. Typical grades being ASTM A602, A47, A338, A220. Additional applications include welding of all grades of cast iron to mild carbon and low alloy steels. WELD METAL ANALYSIS COMPOSITION % BY Wt.
