摘要: A method of repairing a metallic component, such as a superalloy turbine blade or turbine nozzle, includes the step of preparing the component by stripping the protective coatings from the component. The component is then pre-conditioned for welding by a first hot isostatic process. Once the conditioning sequence is complete, the component is welded using any of a number of welding techniques and by adding weld fillers to the weld area. After the welding step, the component is sealed by a second hot isostatic process treatment performed at conditions similar to the first hot isostatic process. The component is finally prepared for re-entry into service.

摘要: A method of repairing a metallic member, such as a superalloy turbine blade, includes the step of preparing the blade by stripping the protective coatings from the blade. The blade is then pre-conditioned for welding by a first hot isostatic process. Once the blade conditioning sequence is complete, the blade is welded using a laser welding technique and by adding weld fillers to the weld area. After the welding step, the blade is sealed by a second hot isostatic process treatment performed at conditions similar to the first hot isostatic process. The blade is finally prepared for re-entry into service.
摘要翻译: 修复诸如超级合金涡轮机叶片的金属构件的方法包括通过从刀片剥离保护涂层来制备刀片的步骤。 然后通过第一个热等静压过程对刀片进行预处理以进行焊接。 一旦刀片调理顺序完成,刀片将使用激光焊接技术进行焊接,并通过在焊接区域添加焊接填料。 在焊接步骤之后,通过在与第一热等静压过程类似的条件下进行的第二次热等静压处理来对刀片进行密封。 刀片最终准备重新投入使用。
