Abstract: A method for repairing a steel alloy article, and an article repaired thereby, is provided and comprises the steps of depositing at least a first weld repair layer on a surface of the article so as to form a heat affected zone in the article beneath the surface. Locally heat treating the first weld repair layer and at least a portion of the heat affected zone adjacent the first weld repair layer at a temperature above the critical A1 temperature of the steel alloy article. Depositing at least one additional weld repair layer on the first weld repair layer without forming additional heat affected zone in the surface of the article. The first weld repair layer and the at least one additional weld repair layer are comprised of a material chosen from the group consisting of nickel chromium—iron alloys, cobalt base alloys, ERNiCr-3, ENiCrFe-3, ERNiCrMo-3, ERNiFeCr-2, ERCoCr-A, ERCoCr-E, CrMo alloys and CrMoV alloys. The article can be placed in service without a post-weld heat treatment of the additional weld repair layer following the step of depositing the additional weld repair layer.

Abstract translation: 提供了修复钢合金制品的方法和由此修补的制品，并且包括以下步骤：在制品的表面上沉积至少第一焊接修复层，以便在制品下面形成热影响区 。 在高于钢合金制品的临界Al温度的温度下，局部热处理第一焊接修复层和与第一焊接修复层相邻的热影响区的至少一部分。 在第一焊接修复层上沉积至少一个附加的焊接修复层，而不在制品的表面中形成额外的热影响区。 第一焊接修复层和至少一个另外的焊接修复层由选自镍铬铁合金，钴基合金，ERNiCr-3，ENiCrFe-3，ERNiCrMo-3，ERNiFeCr-2的材料组成 ，ERCoCr-A，ERCoCr-E，CrMo合金和CrMoV合金。 在附加的焊接修复层的沉积步骤之后，可以在不进行附加焊接修复层的焊后热处理的情况下使用该制品。
