A Ni-Cr-Fe alloy in the form of a weld deposit, a welding electrode and flux and a method of welding utilizing the Ni-Cr-Fe alloy. The alloy comprises in % by weight: 27-31 Cr, 6-11 Fe, 0.01-0.04 C, 1.5-4 Mn, 1-3 Nb, up to 3 Ta, 1-3 (Nb+Ta), 0.01-0.50 Ti, 0.0003-0.02 Zr, 0.0005-0.004 B, < 0.50 Si, 0.50 max Al, < 0.50 Cu, < 1.0 W, < 1.0 Mo, < 0. 12 Co, < 0.015 S, < 0.015 P, 0.01 max Mg, balance Ni plus incidental additions and impurities. The welding method includes welding using a short arc wherein the distance from the electrode tip to the weld deposit is maintained at less than 0.125 inch. |
