ABSTRACT:
The invention provides a welding material for welding iron containing low CTE alloys. The filler metal contains 25-55% nickel, 0-30% cobalt, 0.05-0.5% carbon, 0.25-5% niobium and balance iron with incidental impurities. The welding material also is operable with fluxes for submerged arc welding. In addition, the welding material may be configured to function as a flux coated or flux-cored electrode.
