摘　　要：The effects of the addition of O - 1.2wt. % Ni and 0 - 2wt. % Co in F92 steel weld metal on its A L temperature was analyzed using computational thermodynamic software （ Thermo-CalcTM ） in this paper. The results indicate that both Ni and Co decrease the A, of P92 .steel weld metal, and each elements has a pronounced linear relationship with the At. The il^fluence of Ni on A,I is much larger than that of Co. In order to evaluate effects of Co and Ni in combination on AI of P92 .steel weld metal, an equation Ni = Ni ＋ O. 096Co was developed. According to the formula, the decreaing effect of Co on A., is jun about 1 / 10 of that of Ni. For welding consumables of P92 steel, the .substitution of Co for Ni （part or whole） could be an appropriate way to avoid the strong reduction of A and improve the properties of weld metal.The effects of the addition of O - 1.2wt. % Ni and 0 - 2wt. % Co in F92 steel weld metal on its A L temperature was analyzed using computational thermodynamic software （ Thermo-CalcTM ） in this paper.
