LANCASTER ALLOYS COMPANY OFFERS A NON CONVENTIONAL SOLUTION TO A CONVENTIONAL PROBLEM IN THE MANUFACTURE OF NICKEL ALLOYS
Through the years, welding of nickel filler metals to parts of nickel based alloys has been somehow unpredictable. This is mostly due to the way commercially produced nickel alloys welding wires are drawn. The commercial type of drawing, using lubricants, grease or drawing compounds, imbeds them underneath the surface of the wire as it is being “pulled” through dies in the reduction process. This, in turn, causes sub-surface contamination which usually leads to an unstable weld with porosity, cracks and uneven uniformity. Lack of cleanliness and a wide variety of impurities in nickel alloys are the major reasons for rejection of the welds.
