The nirtogen contents of Ni-Fe, Ni-Cr and Ni-Fe-Cr weld metals deposited in nitrogen or air were systematically determined. Some of them were compared with the solubility of nitrogen measured in an equilibrium state at 1600℃. The main results obtained are summarized as follows : 1 The nitrogen content of Ni-Fe alloy weld metals increases continuously with the iron content of electrode wires. More nitrogen is absorbed in an air atmosphere than in a nitrogen atmosphere. 2 The nitrogen content of Ni-Cr alloy weld metals increases with the chromium content of electrode wires. Less nitrogen is absorbed in an air atmosphere than in a nitrogen atmosphere. 3 The nitrogen content of Ni-Fe-Cr weld metals is influenced greatly by the chromium content of electrode wires. 4 The nitrogen contents of Ni-Fe-Cr weld metals were shown with contour lines of iso-nitrogen content in a ternary diagram.
