Abstract

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°C. 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.
